Sorry, I meant 'type of the superclass' rather than 'superclass'.
I was suggesting that super().m should be
rather than type(self).__mro__.__dict__['m']
(ignoring descriptor __get__ calls)
Unfortunately this brings its own problems, due to __getattribute__
doing its own traversal of the mro.
So, scratch point 1.
