I am puzzled.
How do you attempt to inherit from the base class of polynomial rings?
If one defines something like
class Foo(Bar):
def __init__(self, *args):
<do something special for Foo>
Bar.__init__(self, *args)
then of course the Foo instance "self" is also an instance of Bar, and
the init works. Why does it not, in your case?
