If we were to create a Rust version of this page for Haskell, what cool programming techniques would you add to it?

minus-square@[email protected]linkfedilink2•5 hours agoEnum constructors are functions, this typechecks: fn foo<T>() { let f: fn(T) -> Option<T> = Some; } I was a bit apprehensive because rust has like a gazillion different function types but here it seems to work like just any other language with a HM type system.
