[swift-evolution] Public classes with private superclass

Personally, it's perhaps more of an "aesthetic" thing I suppose but I would definitely prefer that my internal classes stay internal even if there is a public subclass... I don't like how that leaks my internal implementation like that...

Though maybe the more swift thing to do would be to use private extensions in place of private superclasses I suppose...
