At #11900 and [http://groups.google.com/group/sage-combinat-
devel/browse_thread/thread/99c74827d704e677 sage-combinat-devel], as well
as in some comments in sage/categories/category.py, the idea was discussed
to make, for example,
`Algebras(GF(3)).parent_class==Algebras(GF(5)).parent_class` - hence, make
the parent/element classes as independent from the base of a category as
possible.

Comment(by SimonKing):
Replying to [comment:2 SimonKing]:
> I suggest that I create patches for both 2. and 3., and then people can
tell what they think about it. The method resolution will then be taken
care of by another patch.
I just argued myself into splitting the ticket: This here will be for the
base ring independent parent/element classes, and another one will be for
method resolution order.
