What exception would it catch, though? Catching something as
generic as TypeError would be a very bad idea, I think -- there
would be too much potential for it to mask bugs.

It might be acceptable if there were a special subclass of
TypeError for this, such as NotComparableError.

What happens in Py3 here, BTW? It must have the same problem
if it refuses to compare some things for equality.
