Proposal to add a fun currying syntax for nested function calls

[eliassjogreen]

This is an quite old idea but it would essentially allow for a function to be called in multiple different stages before finally executing:

fn bake_a_cake(first: str)(second: i32)(third: bool): str {
  // function body goes here
}

It could then be called like:

val first: fn((second: i32)(third: bool): str) = bake_a_cake("add something")
val final: str = first(123)(false)

This would probably require an auto or automatically inferred type along with a fn type for function references.
