<gcd/> and <ggT/>:

Language issues aside, is it really sensible to have "gcd" hard-coded
at all?

For integers it's well-defined if one insists, as usual, that it be
positive, and for the ring of polynomials over a field, it's
well-defined if one insists that it be monic.  Beyond that it might
just exist as an ideal, i.e., may not have the same type as its
arguments.

I would submit this as an instance where "less is more".
