The only way this could be done would be to do so in an "opt-in"
fashion. E.g. something like:
But even that would be global for a given instantiation of the python
interpreter which isn't really very good either if you need to mix new-
style-expecting and old-style-expecting classes.
So it really doesn't esem worth it, given that people can mixin object
themselves if they desire.
