I'm not sure I understand why much anything would have to change.  My
'lexicographic_mro()' and 'weighted_mro()' linearizations utilize the
existing method resolution order (object.mro()) for the heavy work.
What improvement would a change to this offer?

Of course, the way I set up my sample, it is simple to plug in your
favorite linearization technique.  This is a rough area in my knowledge,
so I'm not religious in my preference for a particular style.

Yours, David...
