Comment(by novoselt):
I am fine with the optimization, I just didn't quite get it before.
Default arguments can work with `UniqueRepresentation`, they just require
more work.
http://www.sagemath.org/doc/reference/sage/structure/unique_representation.html,
section "Argument preprocessing." It was quite interesting to read it, I
didn't know about this class before I saw it in your patch.
My question is not about necessity of `UniqueFactory`, but about necessity
of both `FormalSums` and `FormalSums_generic`. It think that after your
refactoring the answer is no.
