Comment:

 Factorization is aimed to be a generic class, not only polynomials. I am a
 little bit worried about your one line change (and patchbot as well). For
 example the free group has no base ring and matrix groups (`GL` or `SL`)
 have no multiplication defined with element of the base ring.

 Note that some of the patchbot issue is just because `_repr_` of
 `Factorization` is bad. I will add a commit for that.
