Comment:
Bug fixed: I added tests for when the resulting value is either 0, or a
nonzero constant, in which case an element of the base ring is returned.
Otherwise an element of the parent is returned (so you can still evaluate
f(x+y,y) and similar.)
Patch up as soon as testing is finished.
malb: I'm CC-ing you as the past person to work on this file.
