I think you mean Left. And Left in Fin is Error, which has two subtypes: Expected and Exceptional, along with bespoke matching primitives for exceptional and non-exceptional errors (for the reasons I outlined) I understood what they meant,

If you ask yourself what the meaning of the word 'exception' is and then consider how many failures are exceptional , then one quickly realises that exceptions are the worst thing you could use to represent expected failure con

On your definition of FP you're right. But pure functional programming has the following over regular imperative coding: * Fewer bugs: Pure functions, which have no side effects and depend only on their input parameters, are easier

Fair enough :) By the way, I happen to agree on the general point, in my blog teaching Monads in C# [1], I wrote this: "I often see other language ecosystems trying to bring monads into their domain. But, without first-class support f

In C# you can implement SelectMany for a type and that gives this: from id in ParseId(inputId) from user in FindUser(id) from posts in FindPostsByUserId(id) from res in DeactivateDecision(user, posts) select res;

Yes, that's the limitation until the value-type DUs arrive in C# 15. In previous versions of language-ext, I defined Either as a struct with bespoke Match methods to pattern-match. But once pattern-matching appeared in C# proper, it di

I think you're describing part of the bind function, which is part of the definition of the monad interface: a -> m b But the full definition is: bind :: (a -> m b) -> m a -> m b In C#, it would look like th

Not discriminated unions, but they're coming (I think next version of C#). Although for now you can simulate them quite easily: public abstract record Either<L, R>; public sealed record Left<L, R>(L Value) : Eithe

This is all very basic, instead you can use C#'s new static interface methods feature to create higher-kinded traits where you can properly generalise over a monad trait (or applicatives, functors, foldables, etc.), which is what I do

People with mental health issues need help and support. Just because there’s a pithy saying, doesn’t make it universally beneficial to have suffered hardship. Not sure what else you’re expecting? I’m not advocating imposed hardship, just tr

As someone who has had some serious hardship and is certainly more resilient because of it, I can also confirm the mental scarring that comes as ‘part of the package’. I think to an extent the mental impact of it is a necessary evil. The fu

That’s still a poorly designed system. For UI there should be a ‘view model’ that augments your model, that view model should be able to represent every state your UI can be in, which includes any ‘intermediate’ states. If you don’t do this
