Good point. I was going to suggest breaking out the protocol into a
general swift version and have an objective-c specific one refine it,
but in the case where bridging to other languages happens, those other
language specific bridging protocols wouldn't be able to refine the
generic base protocol for types that want to bridge more than one
language. I formally retract my concern :)
