Comment (by kcrisman):
Glad I ran the tests - this is a good one to have fail, though :-)
{{{

I do love that we code errors in the tests, because it's always gratifying
to see when someone has fixed one. (Can you think of another way to test
that error branch, incidentally? I have to admit I can't offhand, unless
it's a (very unusual!) Sage symbolic function not in Sympy, maybe
something number-theoretic, or maybe just a fake function?)
