Comment (by bhutz):
Well, just like is_morphism for polynomials, if given a ring, you can
change to the fraction field. The real question is should that be
implemented here or in dimension. Since improving dimension is more than a
trivial project, I'd say to do the same thing here and when dimension is
improved it can be updated.
I don't think there are any adverse implications for changing to the
fraction field (since dimension = dimension_relative), but I'll think some
more about it when I review the updated version.
