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.
