I'm not sure if this is a definitely bad thing. Let's assume I have a 
number of funcs with similar but different labels and I want to define a 
function variable with another labels and assign one of these funcs:

func foo(one: Int, two: Int) {..}
func bar(first: Int, second: Int) {..}

var a : (alfa: Int, betta: Int) -> () = foo
a(alfa: 1, betta: 2)
a = bar
a(alfa: 1, betta: 2)

But the type of `a` is still (Int, Int) -> () the same as for `foo` and `bar`
