Say you have the function `foo() -> Int`. Then `foo()` calls `foo` and returns its return value of type `Int` – not a reference to the function of type `Void -> Int`.
As to `_`: Like I stated in the proposal the underscore is already used in functions to state that there is no parameter name. So I think it’s a natural extension to also use it for saying that there are no arguments at all. – Alex > On 05 May 2016, at 17:21, David Sweeris <daveswee...@mac.com> wrote: > > What’s wrong with `foo()` again?
