Replying to [comment:13 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 think it would also be useful for specialization in families.

have me take your flatten.py and flesh it out?
I guess the flattening can be done in another ticket. Concerning this one,
it can either wait for flattening or it can be closed and refactored later
on. If you have time for working on it please go ahead.
