Hi everyone, Is there some reason why a generic change_ring() was not implemented for all ideals? This leads to a bug with univariate Laurent polynomials:
sage: L.<t> = LaurentPolynomialRing(QQ) sage: I = L.ideal(0) sage: I + I --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) ... AttributeError: 'Ideal_1poly_field' object has no attribute 'change_ring' I imagine that just calling "return self.ring().parent().ideal(self.gens())" would work in general (and I think should for that matter). This was noticed on PR #36368, where the author is working around it by implementing this for the class in question.
