Yes, you raise good points.
My solution is nice (IMHO) for the simplest use case (and, probably, the
most frequent) but it's behavior is really unclear for these complex use
cases. Thanks for pointing that out.
As far as I'm concerned, I can only confirm that having a super keyword
with methods attached (like Aahz said) when no other keyword has (and
there are many) doesn't feel right (to me) and can be confusing at
first. That's unfortunate as I rarely found python confusing up to now
(contrary to other languages).
The only other option that comes to my mind is using a special attribute
in the instance itself (like __class__, __dict__, ...):
I'm sure this (again) introduces other problems I simply overlooked, in
this case, forgive me please. ;-)
Thanks again for your attention.
