Useful for bringing functional style to C# codebases
From 2 comments
Our organization (big C# codebase, newer apps in scala) has doubled down on extremely functional C# (using the NICTA XShapx library which has a lot of overlap with this one).…
runT1ME on HN> Why bent C# until it looks like something that already exists? Because in the industry at large, JVM == Java and .NET == VB.NET == C#. So bending Java, C# and C++ to have…

Option design that forces handling of None
From 2 comments
Funny I come across this today. Only yesterday did I start turning some of my helper functions and extension methods into a little NuGet library. It's amazing how much overlap…
steego on HNThat's fair enough. I knew implementing it this way would ruffle a few feathers, and I totally understand why. I too would love to see ("a","b"), and proper pattern matching...…

Objections
Option should preserve null or be algebraically consistent
From 2 comments
Coercing Some (null) to None seems like a bug. Null is a valid value in the type and should be allowed (F# allows it too). Otherwise, a function might accidentally return None…
MichaelGG on HNA comment on the option type: I think transforming Some(null) into None is wrong. - There is an x for which Some(x) is not a Some. This violates useful invariants. -…

Unidiomatic C# and lowercase function names
From 2 comments
This is a really interesting experiment, although personally I'd find using: var ab = tuple("a","b"); awful. It's very hard to read what is going on here- someone else reading…
martijn_himself on HNThis is a really cool exploration project, but hopefully I will not see this in any production code. Way too un-idiomatic.

Why not just use F# instead
From 2 comments
I hope this does not come across to negative, definitely a nice project, but is this really useful in practice? If you want F# or Haskell syntax, why not just use F# or Haskell?…
danbruc on HNI am not saying the functionality is useless, but it already exists in other languages. Why force C# to look and behave like F# instead of just using F#?

Questions
Does Option<T> parameter still allow null
From 1 comment
Cool stuff. Isn't there still a problem with Option, where when a method takes Option<T> as a parameter, invocations can pass null for that Option<T>? So there's still the…

danbruc on HNJust use F# from Xamarin. It's the real deal. C# is just a stop-gap measure to suck in the enterprise devs.

Feel free to pilfer some ideas from my own take on a similar lib for C#. https://github.com/danstone/lambit - includes some basic pattern matching support for example. This sort…
