I've read this now and I agree: we should adopt C3.  I *think* that
the current MRO algo is the same as the algorithm called C*[LOOPS] in
that paper; for all cases where they show how C*[LOOPS] differs from
Dylan or from C3, Python gives the same result as C*[LOOPS].

I wish I could find a clue in the Metaclasses book, but it's hard to
search a 300-page book for an occurrence of reference [7]. :-)

BTW for people coming late to this discussion, please read up on MRO
(Method Resolution Order) first here:
