Hi Justin,

This is a Python thing as "==" is equality testing and "is" is memory
address testing. For example,
sage: a = 2
sage: b = 2
sage: a == b
True
sage: id(a)

I think that reverse is it's own inverse. Does anyone else agree?
(The issue is probably just reversing the coefficient list and not
considering degrees.) Thanks for opening tickets mabshoff.

Whilst looking at some code, I noticed that a computation was being

Here's a minor issue with your patch to axiom.py.
I noticed that you included a hack for Axiom function names with ? and
