Comment (by AlexGhitza):
Looks good. I have some questions about {{{_ensure_is_compatible()}}} in
modform/element.py
1. I guess I don't quite know what the function is meant to be used for;
the docstring says "compatible for arithmetic and comparison operations".
I assume arithmetic here means addition or subtraction?
2. With the patch, two forms of the same weight but different groups of
the same level are deemed compatible. For instance, if f is on Gamma0(11)
and g is on Gamma1(11), or if f and g are on Gamma1(17) but with different
Dirichlet characters. Is this the desired behaviour?
