While reviewing some code, I realized that the following is currently allowed: P.<x,x,x,x,x,x> = PolynomialRing(QQ,6) P
Multivariate Polynomial Ring in x, x, x, x, x, x over Rational Field I believe that an object should not be allowed to have repeat instances of the same variable names. I don't get any actual wrong answers, but I feel as if it should be addressed. After looking around, I have found two separate instances in the code base for _assign_names, in category_object.pyx and parent_gens.pyx, both in sage/structure. I think that the code should check for duplicates at this point. However this seems too high up in the sage hierarchy for me to want to mess around with it in good conscious. Is there any reason the code currently operates as is? Or do people agree that this needs to be fixed? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
