Yes, but Guido hasn't decreed that a.spam(b) and b.eggs(a) are
to have a reflective relationship with each other.

But don't worry - I've belatedly realised that the correct way
to do what I was talking about is to return NotImplemented and
let the interpreter take care of calling the reflected method.
So I withdraw my objection.
