In the following code: sage: R. = QQ[] sage: 2/(2*X) 2/(2*X) Is there a case against simplifying 2/(2*X) to 1/X? If it is a bug, it seems to me that we need a new set of "non_monic_gcd" functions for all ring element classes that uses generic reduction (or is there a less invasive solution?).

In current version of sage you can not have a singular object for k(a) [x] when k is a non-prime finite field and a is transcendental. This is because singular does not support defining such rings explicitly, while if k was prime we had no problem. I don't know what the developers of singular were
