There are some doctest failures (see patchbot). There are some actual changes in output type, but I am not sure if they are (more) correct or not. I would think some of them are actual regressions since they do not contain as much information (i.e., ZZ[x][y]
has slightly different structure for things like factoring compared to ZZ[x,y]
).

I reverted the changes to flatten.py
.

I think I understand what is going wrong with flatten.py
. It is checking the keys in D
, which are actual variables and hence, do not compare with the string values. So the variable names all get included when constructing new_vars
on this line:
new_vars = [[[t for t in v if t not in newD.keys()], b] for v,b in old_vars]
I think I see a good way to fix this. I also am going to do a slight bit of cleanup of that method.

Given that I reverted the changes to flatten.py
and that the previouslyfailing doctests now pass, why was this set to needs_work?

This fixes the failing doctests but addresses the problem in flatten.py
(with some simple cleanup).
New commits:
e938684  Handling flatten.py and some mild cleanup.

I would rather fix the problem than push it off until later.
