I was going for replacing the module's dict with a dict subclass, and
hooking __setitem__ it as an alternative to using settrace to
implement this. It's not allowed, though :(. We also need a way to
say, "replace the dict into which new definitions are falling" so we
can implement decorators inside of class definitions.
