[swift-evolution] [pitch] Eliminate the "T1 -> T2" syntax, require "(T1) -> T2"

[Vladimir.S]

In this particular case I belive

func foo(int: Int) -> (Int) -> (String) -> String

is much more explicit and clear about what is what :

foo(int: Int) returns not Int(that returns then String and then String).

foo(int: Int) return function with (Int) parameter, that return func with 
(String) parameter that returns single String value.
