Comment(by SimonKing):
Replying to [comment:23 nthiery]:
> Just a suggestion: in Category, you may want to put a lazy attribute
_parent_class_from_base_classes, so that the categories that want the
optimization (like Modules or Bimodules) can just do parent_class =
_parent_class_from_base_classes (same for element_class of course)
Excellent idea!
