Multivariate rational functions over the integers mod n

[kaelingre]

Finite field methods are frequently used in many areas of theoretical physics. In particular "multivariate rational functions over the integers mod n" would be a useful addition to flint. Is there an easy way to have such objects, essentially having a similar interface like fmpz_mpoly_q, or are there plans to add this to flint?

I suppose this would be pretty easy to implement with the generic rings interface by Fredrik. Ping @fredrik-johansson

Not that this is directly what you want, but we made an implementation of this around a year ago based on flint multivariate polynomials mod n in our project
