Comment (by nbruin):
Replying to [comment:59 behackl]:
> Do you strongly object against setting this back to `positive_review`?
Yes, because it is parking code in the wrong spot.
Perhaps park your code on
`sage.rings.polynomial.polynomial_element.Polynomial`? Taking an n-th root
of a polynomial via factorization isn't quite as bad as in general.
Since `NumberFieldElement` etc. already provides an `nth_root` method, it
may be sufficient to just provide the method on Polynomial.
