> IMO: I think that if you want to allow factor coefficients then the
answer to your question is 3) you shouldn't expect anything...
I don't think so. A neat trick we should copy from FriCAS is to have a
constructor `Factored` that takes a ring and returns a ring, keeping the
elements in factored form.
So far, however, I do not know how to create a ring in sage...
