Comment:
I've uploaded a patch. Should work under 3.2.rc1 with the patch for #4536
installed (as it uses the coordinates() method of orders).
I've implemented quadratic fields and general absolute fields; it would be
trivial to implement for relative orders too, but there is so much general
brokenness for relative orders that there doesn't seem much point (we
don't even have is_integral() for relative orders yet).
