Issue Description:

func g(_ x: Int, _ y: Int) {}
func h(_ tuple: (Int, Int)) {}

print("Type of g:", type(of: g)) // (Int, Int) -> ()
print("Type of h:", type(of: h)) // (Int, Int) -> ()
// Note that the type of h is printed incorrectly, it
// should be: ((Int, Int)) -> ()

// The types are different however:
print("Type of g == Type of h:", type(of: g) == type(of: h)) // false

Interestingly metatype is printed correctly as `(((Int, Int)) -> ()).Type`
