Comment (by dimpase):
OK, this is easy, I hope. I'll work on this tonight. As far as I
understand, the base ring is RDF for all the backends, expect PPL.
Actually, is it even needed to provide base_ring() in the backends that
have RDF as the base ring? Can't PPL just overwrite it? I gather Python
has such an option:
{{{
class A(object):
...
def a(self):
....
class B(A):
...
def _A__a(self):
...
}}}
so B overwrites A.a() this way. Or is this wrong/not applicable?
