Like just spend a while looking at "blue1" (#0000ff) and "blue2" (#0000ee) right next to each other.
Or tan1 (#ffa54f) and #eea54f.
(I don't remember the exact colours, but I tried to recreate it as good as I could from memory. Just look at these two pictures in big and see if they look like one solid colour or like two completely different ones each - probably didn't do a good job as I don't work with them daily but I hope it is good enough to communicate what I mean)
#ff0000 red
#ff0080 rose
#ff00ff purple
#8000ff violet
#0000ff blue
#0080ff azure
#00ffff cyan
#00ff80 mint
#00ff00 green
#80ff00 chartreuse
#ffff00 yellow
#ff8000 orange
roses are red
violets are blue
i guess to those who
don't care about hue
roses are green
violets are mint
look at their leaves
their chlorophyll tint
roses are orange
violets are azure
your eyes are flawless
my vision unsure
roses are purple
violets are purple
I'm colorblind
I fancy your curple

Denkmal an der Stelle der Schrippenkirche
Wie wohnten die Menschen in „Meyers Hof“? Wer ging in die „Schrippenkirche“? Und an wen konnten sich obdachlose Frauen um 1900 wenden? Die „Berliner Spurensuche“ lud zu einer Führung zur Geschichte der Armut im Wedding an. Ein Dutzend Interessierte kamen, um sich bei schönstem Sonnenschein vom Historiker Stefan Zollhauser über das Leben armer Menschen, über solidarisches Miteinander und Erinnerungsorte der Armut informieren zu lassen. Unsere Autorin war dabei.

#SmallTalkSavesLives?? DANGEROUS Samaritans Ads
Upfront to anyone who lives in London and struggles with life, suicidal thoughts, I have visited The Listening Place (TLP), based in Pimlico twice, once in 2016 and again 2018. They were started by 2 former Samaritans who felt the need to start a face-to-face charity as a need to address suicidal crisis in person.
I was one of the first, if not THE first “client” when the Mind charity in Pimlico let them use some rooms before TLP moved to their own facilities down the road. On both occasions/years I have nothing but good things to say about them (and hope they are still the same).
It’s by appointment only. Please see link to The Listening Place.
.
Also, little side-note, the Samaritans social media team on Facebook blocked me after I pointed out the below in a much shorter text. So far to how much they really care. And no, I wasn’t rude or used any swear words.
Also at the bottom of this page about the poor scoring on Trustpilot. Here’s just one of many reviews, and then it makes sense why Samaritans “recruit” members of the public:
.
Important UPDATE April 2024 at the bottom of this post HOW the Smaritans started.
UPDATE 14. August 2024:
“Sexual harassment against women and girls up 50% on British railways”
UPDATE 2025: Trustpilot reviews at the very bottom of this page. 80% (1 & 2 star reviews combined) disapprove of Samaritans. When I saw the percentage, I thought I accidentally went on the Pret A Manger Trustpilot reviews as they also have 73% disapproval rate.
.
Poor quality Audio Version via “AI” conversion. Apologies for the lack of crisp quality. This is for people with visual impairment where “AI” programs can’t read screenshots. I briefly explain via audio what the videos and photos show. Please note, the audio is NOT updated with any of the text updates here.
.
.
The Samaritans together with Network Rail and Transport Police have brought out an ad campaign to prevent suicide. The way they’re doing this had me shocked and many women and some men outraged on Twitter/X.
Four such ads appeared in a row within days. The slogan is “Small-talk saves lives” under the hashtag #SmallTalkSavesLives.
There are SO MANY issues with this ad.
All my red flags went up when I first saw the ad on X. And as someone on the other side of this, struggling with suicidal thoughts at times, I am appalled!
In the UK, especially in London, attacks and sexual assaults have increased, EVEN in broad daylight on trains and stations etc. And yet, Samaritans, Police and Rail company want WOMEN to approach complete strangers to start a conversation.
One, you can tell that MEN must have been behind that ad. EVERY woman has at one point or another been sexually assaulted, often since childhood and repeatedly. And they know that! Although the CEO is female and the lead psychologist coming up with this ad is also female. It’s the way women are raised.
Two, these men who run the ad campaign, and especially money-saving railway and police want women again to do the heavy lifting and emotional labour.
Three, and even worse, they want UNTRAINED people to deal with extreme mental health crisis of strangers.
And four, to do this with “small talk”!
I struggle with suicidal thoughts. It has become much less, but it is always at the back of my mind! Small-talk is THE LAST thing I want. I never liked small-talk to begin with! And I certainly won’t want a stranger, especially a man to approach me doing small-talk during a mental health crisis! Let alone a woman approach a man!
Also, many people just look tired or sad, after all we live in a busy city. But for the Samaritans to want people to assume someone is suicidal and strike up a conversation is horrendous. I often look sad, even before my brother died I had a serious look on my face because I’m a thinker! People often commented on my serious looking face. I’d be so offended if I was NOT suicidal and someone assumes this and then starts a chitter-chatter!
This ad campaign feels like a lazy cop-out by mental health services as the NHS is overstretched, to “employ” free mental health workers who are NOT qualified, and then to approach strangers. And they appeal mainly to women to do the work!
I am absolutely appalled. And since the comments on X went through the roof, Samaritans have added a post 4 days later adding that people should call 999 if they’re not comfortable. Well, dah!
I and many others have appealed to Samaritans to drop the ad, or at least use MEN to talk to MEN!!!
“Small talk can take lives”!
Here are the examples, with the last video being THE WORST ad I’ve ever seen on any subject!
The first one is, again, women pampering men in the name of free treatment to “save a life”! My stomach’s turning! And please know this is not an anti-men blog post! I’m neither gay nor anti-men, and I know there are more good men in the world than the creeps who fill the news! I love men, I appreciate men, I feel good around great men! This is about the coercion of females and their empathy again.
Next:
“Something didn’t feel right. … Just that one little bit of positive small talk and it can go so far.” Yep, it can go so far! It can get you raped or killed! Women are told to FEEL something and make assumptions to approach men to chat!
Really? People sit in a nail salon telling the staff they feel/felt suicidal? And then some small-talk does the trick?
How much did those ad campaigns, especially the videos with actors cost??
And the absolute worst and DANGEROUS ad, telling women to “trust your instincts” while in reality gaslighting them to OVER-RIDE / IGNORE / QUESTION their instincts! Link to the video below as well.

In case Samaritans delete the video, here’s another LINK.

REMINDER
Sexual and other assaults on women and girls on railway and tube has increased by 50% in the last 2-3 years. It has DOUBLED!
And this is only on public transport!!! We don’t know what the numbers are on the street and behind closed doors.
The stastistic is NOT that male suicides on railway and tube is up by 50%, but assault on females. WHERE are the campaigns for men to step up and look out for women’s safety instead of being SPECTATORS while women get raped and assaulted?! Because we live in a porn sick society, where porn and prostitution has been normalised.
Shame on Samaritans, Network Rail, and unsurprisingly Police for the lazy and money-saving aim to coerce women to approach men and play saviour again!
.
.
I say it again, women are being told to “trust their instincts” while in reality being coerced to IGNORE / OVER-RIDE their instincts and approach complete strangers on a train platform for small talk!
One guy on X tried to guilt-trip me, and make me responsible if a man dies by suicide. I responded that I’d rather hurt his (the X poster’s) feelings than endanger my life. I made it very clear that if I think he or someone is about to end their life, I WILL call for help!
I will NOT, as a lone woman on a platform close to the edge start “small talk” with a man who looks sad or tired or whatever! I will look for staff, call mental health service or even police depending on the situation! ! ! !
But I will NOT approach a stranger to start a conversation! It is NOT my job to be the saviour of strangers and make assumptions about someone’s mental health state! ! ! !
What’s also so appalling in the ad is that behind the “assumed” suicidal man is a MALE staff member with orange vest! But it’s the woman who is implored to talk to the man!
I raised this with Network Rail saying that this is clever to manipulate people to think you’re not alone and there’s staff close by! I NEVER see ANY staff on platforms anymore!!! And then, why is the trained staff member not implored to speak to the man?!
It’s clear why! Women are being lured into danger at worst, or to do the heavy lifting in emotional labour at best.
I say it loud and unashamed, do NOT approach a stranger on a platform, but call for help! End of!
I speak openly about my struggles to take the sting out and release the “mystery” of such horrible thoughts to lighten the pain.
I wrote a blog post years ago briefly linking to helplines that have helped me personally:
But the Samaritans have lost me here.
One tweet gave the CORRECT approach and it’s appalling that Samaritans want women to approach strangers assuming severe mental health issues. Help someone as a group.
And Samaritans are hiding comments from people, as well as having blocked me on Facebook.
.
.
.
.
Three things:
.
THAT’S how you do it!!!
No “small-talk”, no woman approaching a guy ALONE! Shame on Samaritans and Network Rail, and I’m not even surprised that British Transport Police endorse this.
I don’t expect anything from police with their record of corruption, misogyny, violence against women etc. etc.!
.
Also someone on social media pointing out that suicide is not only due psychosocial reasons.
.
.
And someone else quoted CEO pay. How can a CEO of a MENTAL HEALTH CHARITY get almost the same pay than the Prime Minister of the UK or the President of the USA??
And funds go into media and ads and executives, while the frontline hard work is done by UNPAID volunteers!!! Also, voluteers have NO labour rights under the law like paid workers have. This is all backwards!
.
.
I question the motives of the Samaritans leadership, and I lived long enough to know that for Network Rail (companies) etc. it’s all about money. We live in a world where FREE labour (volunteer work) and low wages are normalised. So, let the public, and especially women, do all the work for free. Appalling!
Now, we mature women see this bullsh!t ad for what it is, aiming to appeal at female empathy, but imagine a teenage girl or even a woman in her 20s seeing such an ad, and them knowing how women’s empathy is being tapped into! She takes this on and assumes she can or “HAS TO” save a man who stands there staring into air! FFS! Women are drilled from childhood on to submit, to shush, to serve, to save! And they know that very well. And many women, like the CEO and the lead psychologist cater to this as well.
If you don’t read anything else, please read the following review by an ex-Samaritan volunteer!!!
.
Female volunteers are STILL coached to go along with sex calls! (Please see infobelow n the “Brenda” line).
Where is the MeToo movement when we need them?!
.
.
Reading these reviews by callers and volunteers alike, it’s very clear that Samaritans TARGET women to save orplease men! Shame on them. These “services” need massive investigation and change!
.
To give UNPAID volunteers SUCH serious, difficult, degrading line of work is not only unfair, but cruel and unethical!
And to any volunteer of any charity, please KNOW that no charity can demand you to commit to work!!! They can only demand PAID employees with a contract, but not unpaid volunteers. Volunteer have NO rights and also cannot be forced to commit.
Here just a few of the many horror news on women being pushed unto traintracks or women being raped, sexually assaulted on trains, platforms in broad daylight. I only link to the news without showing pictures. Yes, this is done to men as well, but we all know the statistics of more violence against women by men than vice versa.
It’s the same with vans, I stay away from vans with open door. If I’m called over and asked to help someone get something in or out of a van or car, I decline and respond to ask a shop or men or whatever. Again, I’d rather hurt someone’s feelings than endanger myself.
Not to mention that a predator can pretend to be mentally distressed to lure women in. We already fight against men suddenly identifying as women to get into women’s prisons, women’s sports, women’s toilets, locker rooms, hospital wards etc. etc. And Samaritans want to lure women and girls to save a man via small-talk! Absolute irresponsible sh!t show!
It just seems that the war on women is in full swing. Women have become too independent, strong, self-sufficient, have opinions, leadership etc. they want to rein women in again! We need to fight over and over not just for new rights, but to not lose the hard-fought rights women and men achieved years ago.
And we women know that when we just even smile at a stranger, some men take this as a hint. Let alone strike up a conversation!
.
UPDATE 2025 – The above comment is shown in black and white on a Pret A Manger Twitter comment by a pastor who assumed he was “hit on” by a female staff member because she smiled at him. For one, I educated him that Pret staff HAVE TO smile, or no-one gets bonus, and 2. the fact that some men take a smile, let alone initiation of small-talk as a hint …nothing more to say.
.
.
The following is only in the UK, I can’t be bothered to include other countries:
December 2023 during the MORNING commute: “A woman was raped on the London Underground in front of other passengers. Why did no one intervene?”
(Maybe because too many men are addicted to porn and see assaults like this as normal? Every onlooker’s hard-drive should be checked as well as judges who give lenient sentences to rapists and paedophiles!)
And yes, crimes happen to men too, and women too commit crimes, but we all know that violent and sexual crimes are predominantly committed by men against women and children. And the appalling way judges, the media etc. cater to violent rapists who quickly identify as women to get lenient sentencing and go to women’s prisons, these rapist are called “she/her” in court to put crimes on women! Absolutely fed up with this!
And before anyone says I’m transphobic, fnck right off! I love and support transman Buck Angel, transwoman Blaire White and many others, both who get a lot of backlash, even death threats for speaking sense into this madness! So, try your BS somewhere else!
November 2023: “Woman pushed towards tracks at busy London Tube station after being grabbed by man“
27.02.2024 (yesterday): “Hunt for man who ‘masturbated in front of woman on Elizabeth line train”
August 2023: “Disabled woman describes ‘horrifying moment’ she was sexually assaulted on a train“
2017: “Wheelchair-bound woman pushed on to train tracks and bashed in head”
2019 Scotland: “Street beggar raped woman after she tried to help him“
.
.
And many, many, many more horror stories. So, let’s just send women to strangers for small-talk, hey?!
November 2023 Survey: “One in three women sexually harassed while commuting by train or Tube, survey reveals”
.
.
REMINDER!
Sexual and other assaults on women and girls on railway and tube has increased by 50% in the last 2-3 years. It has DOUBLED!
And this is only on public transport!!! We don’t know what the numbers are on the street and behind closed doors.
The stastistic is NOT that male suicides on railway and tube is up by 50%, but assault on females. WHERE are the campaigns for men to step up and look out for women’s safety instead of being SPECTATORS while women get raped and assaulted?! Because we live in a porn sick society, where porn and prostitution has been normalised.
Shame on Samaritans, Network Rail, and unsurprisingly Police for the lazy and money-saving aim to coerce women to approach men and play saviour again!
.
.
Some of the many comments, these are just some of my favourites, hitting the nail on the head. Emotional blackmail in full swing!
.
.
.
.
.
THIS is my favourite comment, SPOT ON observation!
.
.
.
And many, many, many more. You can look those up on Twitter/X. I cannot keep doing such long blog posts. I think people get the message. Speak to your friends, colleagues, especially female, to truly trust their instincts and NOT over-ride them!
The outcry by mainly women but also several men has led Samaritans to update with the following:
.
.
!!! REMINDER !!!

.
.
But the outcry remains, and people continue to raise their voice for Samaritans to drop the ad or use men to talk to men, in groups!
Do NOT approach a stranger to strike up a conversation / small talk, especially not as women towards men! ALWAYS call for help if you think something’s wrong! And leave the mental health heavy lifting to the professionals.
If you have suicidal friends/family member, and I have burdened many friends, especially in a drunken state, you did the right thing to continue giving mental health links. Don’t abandon the friendship if you can, but you did and do the right thing to call for or point to professionals.
Thank you.

UPDATE April 2024
As I still inform people, especially women on social media on the horrible “Smalltalk” ads, I was linked to an excellent exposé by a blogger who did amazing research into the founder of the Samaritans. PLEASE READ!
Link to Tweet.
Link to blogger’s article: The Brenda Line – Samartitans 2
UPDATE April 2025 – I just found this interview. I had a hunge that a psychologist is behind this ad campaign. And unfortunately a female psychologist who, as many women do, throw other women under the bus. No thought about the dangers, maybe she was protected all her life.
Quote: “We spoke to Dr Lisa Marzano, lead psychologist behind the campaign, who works with the Samaritans Media Advisory Team, and previously British Transport Police, on training staff in helping suicidal people.”
On training STAFF!!!!! But she’s behind the ad campaign guilt-tripping members of the public, especially women to do this work! Appalling!
.
Link to interview.
UPDATE 2025 – I just took a look at Samaritans Trustpilot reviews and they speak for itself.
Link to Samaritans reviews.
Hoping for an undercover journalist to go undercover as a volunteer. And for anyone saying reviews are fake, many people on Trustpilot leave reviews under their name and have a mix of positive and negative reviews on organisations. If people are happy, why should they leave a fake negative review?
But I am very weary of “charities”. It’s always about funding once these organisations grow.
Samaritans score April 2025:
.
.
And the mental health charity Mind, of whom I read someone doing what I do with Pret, calling out systemic workplace bullying within the charity have 95% bad scores on Trustpilot (1 & 2 star reviews combined). If a journalist can go undercover into these “charities”. There’s something really really wrong here.
Link to Mind Trustpilot reviews.
This recent review also talks about Samaritans:
.
.
.
Pret score April 2025:
.
.
I worked at Pret A Manger and survived systemic workplace bullying during bereavement that involved HR, the top leadership, HQ and even the now “retired” former CEO Clive Schlee. Schlee has been appointed CEO of itsu in 2024 by Julian Metcalfe who gave him the CEO spot at Pret many years ago.
I declined 4 settlement offers if I am silent about my ordeal. But I rather speak out to help others. For an overview of important blog entries of my experience with Pret, please visit “My Ordeal with Pret A Manger”. The little arrow to the right next to each heading will lead directly to the post.
An incomplete list on what other Pret staff say about Pret’s bullying environment: Caught in the Act Bullying at Pret and What shop MANAGERS & HQ staff say about Pret incl. CEO Pano Christou.
I tell my story for the first time verbally in below audio player interview on a podcast by The Adam Paradox, and wrote two articles in the Scottish Left Review as well as mentioned by the BBC.

12-13 Novembro de 2025 – Porto
Num momento de crise e encruzilhada da cultura e da civilização ocidental globalizadas, em que por um lado se agravam sintomas disfuncionais, como a degradação da saúde mental, a polarização social e a destruição ambiental, e por outro se verifica uma crescente redescoberta da vida contemplativa e do interesse pela espiritualidade, este Colóquio visa investigar a marcante presença do tema da experiência contemplativa no pensamento e na cultura portugueses, desde o período anterior à nacionalidade até ao presente. Desde as tradições mitopoéticas ancestrais às Cantigas de Amigo, desde as narrativas de viagens marítimas a ilhas paradisíacas – como a Navegação de São Brandão e o Conto de Amaro – à Demanda do Graal e a obras de espiritualidade ascético-mística – como o Castelo Perigoso, o Orto do Esposo e o Bosco Deleitoso – , desde a obra de Santo António de Lisboa e Pedro Hispano à poesia de Luís de Camões e Frei Agostinho da Cruz e aos tratados de teologia e contemplação mística de Francisco de Sousa Tavares, D. Manuel de Portugal, D. Gaspar de Leão, Hilarião Brandão, Sebastião Toscano, Heitor Pinto, Agostinho de Santa Maria, Manuel Bernardes e Soror Isabel do Menino Jesus (entre muitos outros), desde a poesia de Antero de Quental até Guerra Junqueiro, Teixeira de Pascoaes e Fernando Pessoa, desde a filosofia aberta ao inefável de Leonardo Coimbra, Raul Leal, José Marinho, Agostinho da Silva, Eudoro de Sousa, Dalila Pereira da Costa e Vergílio Ferreira à poética do êxtase, do silêncio, do espanto e do maravilhamento em Natália Correia, António Ramos Rosa, Sophia de Mello Breyner, Maria Gabriela Llansol e autores contemporâneos, abrem-se múltiplos caminhos para a exploração deste tema intemporal e muito actual.
Este Colóquio visa rever e repensar o horizonte e as características do pensamento e da cultura portugueses, investigando um dos seus temas maiores que tem permanecido esquecido e encoberto, oferecendo possibilidades e desafios fecundos para a nossa vida presente e futura, entre os quais alternativas à crise da sociedade do trabalho, da produção, do consumo e da distracção que Byung-Chul Han designou como “sociedade do burnout” que convergem com o renascimento do interesse pelo repouso contemplativo, pelas práticas meditativas e pela espiritualidade.

How two primary colors can change a mood. The average human eye can see around one million colors. Yet only two seem to set a mood when combined with images. #FF0000 and #0000FF. Both seem to sit as a combination of numbers and letters of a ying and yang equation. Were you fluent in Pantone Color or color palette, you might say to yourself, “Oh.

Some notes on recursive lambda expressions in case I ever want to try this myself (spoilers: a lot of study time ahead; many of these links are not live any more)
A sidestep of the series around Writing a tool that restarts the Google Chat desktop app Window (and hopefully the Google Duo desktop app Window too):
Enumerating Windows and especially Child Windows is a recursive endeavour, so I wondered if it was possible to write a self referencing delegate, anonymous method or lambda in C#.
That turns out to be way more complicated than I hoped for.
Some notes below, as:
Here we go:
Let’s start with the recursive series that most of the below links use:
Definition:
F0 = 0,F1= 1,and
Fn = Fn-1 + Fn-2for
n> 1The first 20 Fibonacci numbers
Fnare:
F0F1F2F3F4F5F6F7F8F9F10F11F12F13F14F15F16F17F18F1901123581321345589144233377610987159725844181
Definition:
F0 = 1,F1= 1,and
Fn = n * Fn-1for
n> 1
But it is usually written as n! instead of Fn so n! = n * (n-1!) and the first 21 n! values for n are:
nn!0111223642451206720750408403209362880103628800113991680012479001600136227020800148717829120015130767436800016209227898880001735568742809600018640237370572800019121645100408832000202432902008176640000
Factorial numbers grow way faster than Fibonacci numbers, but there are more series that can grow even faster as explained in Recurrence relation – Wikipedia, but I digress.
Then the blog posts:
This is a very geeky post. The tiny piece of useful information comes right at the bottom. The rest of it is all artifacts of the obscure art of doing lambda calculus in C#, which can also be characterized as doing very much with very little, sacrificing only readability.
so basically: it can be done, it is ugly, do not use it if you can avoid it.
He continues:
People sometimes complain that you cannot write a lambda expression that is recursive. Good old factorial, for instance, how to write that as a lambda expression? Well the fathers of lambda calculus, who invented the lambda expressions in the 1930’s struggled with that, too, and as you might have guessed they came up with a solution.
In this post let us stand on the shoulders of those giants and see how you can get recursion into your own lambda expressions in C#. It may not be practical but it is fun!
and the final part of the post is showing how ugly:
Admitted it ain’t pretty:
i => new Func<Func<int,int>,Func<int,int>>
(fac => x => x == 0 ? 1 : x * fac(x - 1))
(new SelfApplicable<Func<Func<Func<int,int>,Func<int,int>>,Func<int,int>>>
(y => f => x => f(y(y)(f))(x))(y => f => x => f(y(y)(f))(x))(fac => x => x == 0 ? 1 : x * fac(x - 1)))(i)

Note that we had to actually name the lambda in order to implement the recursion. Without a name, how would you make the recursive call? This self-referencing places some restrictions on how a recursive lambda can be used; the lambda doesn’t refer to itself, it refers to
fib1, which happens to be itself.
[Wayback/Archive] Stupid Lambda Tricks – Visual C++ Team Blog – Site Home – MSDN Blogs – page 2 has the rest of the comments.
This blog post also links to a great article below from Bart de Smet.
<code> tags removed which might have influenced the code itself too (on my content management systems occasionally does), so here are quotes from the content with those [Wayback/Archive] <code> : The Inline Code element – HTML: HyperText Markup Language | MDN in it as it shows how to create the Y-combinator:Lambdas are anonymous functions and recursion requires names. Let’s try to define a lambda that computes the nth Fibonacci number.
Func<int, int> fib = n => n > 1 ? fib(n – 1) + fib(n – 2) : n;
But this doesn’t work. The compiler will complain about the use of fib in the lambda.
Use of unassigned local variable ‘fib’
… The problem is that the right hand side is evaluated before fib is definitely assigned.
…
Recursive returns a function (the effect of currying it) which takes the second parameter of the original definition and returns the original return type.
delegate Func<A,R> Recursive<A,R>(Recursive<A,R> r);
…
Parameterizing the types used by CreateFib leads to what is known as the Y fixed-point combinator.
static Func<A, R> Y<A, R>(Func<Func<A, R>, Func<A, R>> f)
{
Recursive<A, R> rec = r => a => f(r(r))(a);
return rec(rec);
}We can now create any recursive lambda of one parameter that we want.
Func<int,int> fib = Y<int,int>(f => n => n > 1 ? f(n – 1) + f(n – 2) : n);
Func<int, int> fact = Y<int, int>(f => n => n > 1 ? n * f(n – 1) : 1);
Console.WriteLine(fib(6)); // displays 8
Console.WriteLine(fact(6)); // displays 720Finally, the goal of anonymous recursion has been reached.
In the comments, he then shows the same
Action<T>Y-combinator that Eric Lippert shows below on Stack Overflow:delegate Action RecursiveAction(RecursiveAction r);static Action Y(Func<Action, Action> f){ RecursiveAction rec = r => a => f(r(r))(a); return rec(rec);}Of course, you can use the function Fix instead of Y to do this which is more performant.
delegate Action RecursiveAction(RecursiveAction r);static Action Y(Func<Action, Action> f){ RecursiveAction rec = r => a => f(r(r))(a); return rec(rec);}Of course, you can use the function Fix instead of Y to do this which is more performant.
Be sure to read the other comments there as well as they also describe the memoisation optimisation that Bart de Smet writes about below.
At a given location in the executable code of a function member, a variable is said to be definitely assigned if the compiler can prove, by static flow analysis, that the variable has been automatically initialized or has been the target of at least one assignment.
In functional programming, the Y combinator can be used to formally define recursive functions in a programming language that does not support recursion.
code markup.What if we wanted that last one to use lambdas?
static void PrintTree(Tree t){ Traversal df = (t, a)=>{ if(t==null) return; a(t.Value); df(t.Left, a); df(t.Right, a); }; Traverse(t, df, Print);}That doesn’t work because it’s a definite assignment error. The compiler says that local variable
dfis being used before it is assigned. You’d have to sayTraversal<T> df = null;df = (t, a)=>{And suddenly it would start working.
The reason this is an error is because though there is actually no definite assignment problem here, it is not too hard to find a similar situation which does create a problem. Here’s a silly example that nevertheless demonstrates a real problem:
If you trace out the logic of that thing you’ll find that in fact the local variable delegate d is potentially used before it is initialized, and therefore this must be an error. We could immensely complicate the definite assignment rules by adding rules to discover which lambda and anonymous method bodies are guaranteed to be never called during the initialization, and therefore suppress definite assignment errors on some locals in their bodies. But one of the goals of the standardization process is to make rules that are clear and unambiguous and comprehensible by mortals; enabling recursive anonymous methods isn’t a big enough win for the amount of complexity, particularly when you consider that there is the simple workaround of assigning todelegate D D(D d);//...D d = ((D)(c=>c(d))(e=>e);nulland then reassigning.
Note that in practice though, assigning null will not capture that value, but still capture the variable (including the new assignment) and use the captured variable in the lambda.
Func<uint, uint> fib = null;
fib = n => n <= 2 ? 1 : fib(n – 1) + fib(n – 2);The reason we need to spread this across two lines is interesting by itself. If we don’t do this, the following error appears:
memoize.cs(17,48): error CS0165: Use of unassigned local variable ‘fib’
referring to the highlighted position in the code:
Func<uint, uint> fib = n => n <= 2 ? 1 : fib(n – 1) + fib(n – 2);
The reason this error pops up is because we’re defining a function in terms of itself, something that’s invalid in a variable declaration/assignment in C#, just like the following is invalid:
int a = a + b;
Then he gets to the point about explaining what happens when the statement is spread across two lines: the variable fib (and not its initial null value) is captured in the n => n <= 2 ? 1 : fib(n - 1) + fib(n - 2)lambda expression:
But what are we doing really when declaring the following?
Func<uint, uint> fib = null;
fib = n => n <= 2 ? 1 : fib(n – 1) + fib(n – 2);When assigning the lambda on the second line to fib, we’re capturing the fib variable itself as it appears in the lambda’s body.
Then he goes on measuring performance of this function, and then injects a memoisation which is plugin compatible with fib and caches intermediate fib results (as fib(n-1) depends on the result of fib(n-2), which results of an order of magnitude performance increasing!)

This seems to be an academic exercise. While it is possible to do, most people feel that it is simply not the headache to create.

Action<T>) using the Y combinator named AnonymousRecursion<A>:A
As others have said, you should simply use renaming tools if you are planning to rename a method.
But it is an interesting challenge to make a recursive function that does not refer to the name of the function. Here’s a way to do it:
delegate Action<A> Recursive<A>(Recursive<A> r);static Action<A> AnonymousRecursion<A>(Func<Action<A>, Action<A>> f){ Recursive<A> rec = r => a => { f(r(r))(a); }; return rec(rec);} Action<string> SelfRef = AnonymousRecursion<string>( f => input => { if (input == "route1") f("route2"); // and so on });Notice how field
SelfRefnowhere refers toSelfRefin its body, and yet the recursion is very straightforward; you simply recurse onfinstead ofSelfRef.However I submit to you that this code is far, far harder to understand and maintain than simply writing a straightforward recursive method.

Further reading for those interessed: Anonymous Recursion in C#
The link fails (because of link rot, but I resurrected it further up in this post), and the question regrettably got downvoted (likely because the use case is not a really good demonstration of why you want such a construct), but the concept it asked for is a great question so I upvoted it.
How I found all this
This was my start: [Wayback/Archive] recursive c# self referencing Action – Recherche Google.
It got me to both the Stack Overflow question above and the 2011 comment.
