Comment:
I think that this is pretty good overall, but the random test is a little
weak, because they are very small polys. Check out a few!
Instead,
{{{
sage: base = QQ['y']
sage: polynomials = base['x']
sage: f = SR(polynomials.random_element(8)); g = f.expand().collect(x);
print f; print g; bool(f == g)
}}}
gives us a more robust one. Can you think of even more crazy ones? We
could do arbitrarily wacky ones... but at least this show the collect in
action; the current test rarely does, as far as I can tell.
