Comment (by jdemeyer):
I'm still not convinced by the `if type(x) is type(y)`. That would break
if somebody wants to subclass `Integer` for some reason. You can check the
types first as an optimization, but you should still support the case
where `isinstance(x, Integer) and isinstance(y, Integer)`.
