Comment(by cremona):
Interesting discussion and patches. Two comments:
1. Do these quotient ring elements really only work for multiple-
variable polynomial rings? That is a pity. I have tried working in
quotients R/I where R is the rings of integers of a number field and I an
integral ideal, but without much joy, and perhaps this is why.
2. Although there are now lots of examples/tests, a lot of functions
still lack the one-line description. (e.g. _integer_(), what is that
supposed to do? I don't believe that there is a sensibly canonical map
from any quotient ring to ZZ!).
