If B is a subclass of A, then I can assign B.self to a variable of type A.Type. However, instantiating an object using that variable creates an instance of A, not B.

Steps to Reproduce:
class A {
    required init() {}
    func printMe() {

class B : A {
    override func printMe() {

var t : A.Type
t = B.self
let b = t()
