Assuming that you are using : for type assignment and -> or => for functions

unlabelled functions would have the syntax  Int => Int not Int: Int.

So func(int : Int, bool: Bool) : Int  // would return a value

func((int: Int, bool: Bool) : Int => Int would return a function with parameter 
of int and and a function f(i) -> int.
