Comment (by bhutz):
Yes, I wasn't very happy with computing the gcd multiple times, but it did
track the issue and the gcd is faster than the actual division step, so it
wasn't a big performance hit in what we were doing.
I didn't experiment with the flattening code, but that sounds promising. I
think it would also be useful for specialization in families.
Do you want to add the flattening functionality to polynomial rings, or
have me take your flatten.py and flesh it out?
