Thanks Anne. This implements an algebra. I want to have a vector space with
basis
and then construct some operators. Mathematically, this is a module for the
affine Temperley-Lieb algebra.

If I change the first line to
class Foo(Element, UniqueRepresentation):
then when I create an instance and look at it I get
Generic element of a structure

Hi Bruce,
You can check in
sage/src/sage/algebras/affine_nil_temperley_lieb.py
where the affine nilTemperley Lieb algebra was already implemented.
Best,
Anne

I think the Foo class must also inherit from the Element class.

Hi,
I have just pushed my last changes. I'm using both facades and
representations as we discussed. Still two issues :
- the is_parent_of method checks only one level and I would need it to
check all levels
- the problem we discussed already that the category dosen't overwrite
the default parent

I was seeing it the other way arround : the concrete parents giving
their facade parents. This is the way it has to work for me, so
actually, I can't use the "facade" parameter in parents as I don't
know which are the concrete parents when I create the facade.
thank's anyway
