Comment (by vdelecroix):
Replying to [comment:23 pernici]:
> I eliminated `newton_sum`, since it can be inlined, and it is not yet
clear to me which arguments
> `newton_sum` should have (`prec` or `R`), nor what it should return (a
polynomial or a series).
indeed
> Implementing `composed_op` using `flint` would be faster. For instance
in sage it is not
> implemented `mullow`, present in `flint` `nmod_poly`, so that one has to
compute the product of the
> polynomials and then truncate.
