Heh, that's a sneaky way to instantiate a class without actually
instantiating it.

Why didn't I think of this, considering that I once seriously considered
using a sort of mind-swap to let one object assume the identity of
another:

        c.__dict__, d.__dict__ = d.__dict__, c.__dict__
        c.__class__, d.__class__ = d.__class__, c.__class__
