Perhaps we should start emitting a DeprecationWarning for int subclasses returned from __int__ and __index__ in 3.4? (I like the idea of an explicit error over implicit conversion to the base type, so deprecation of subtypes makes sense as a way forward. We should check the other type coercion methods, too.)
