//Class methods and initializers that satisfy protocol requirements now properly invoke subclass
//overrides when called in generic contexts. (18828217) For example:

protocol P {
  class func foo()
}

class C: P {
  class func foo() { println("C!") }
}

class D: C {
  override class func foo() { println("D!") }
}

func foo<T: P>(x: T) {
  x.dynamicType.foo()
}

foo(C()) // Prints "C!"
foo(D()) // Used to incorrectly print "C!", now prints "D!"
