Hi there, many classes in SAGE implement and test for is_zero. I think these methods should be replaced with __nonzero__ methods, as this is the standard way of doing such a test in Python. For example, int doesn't have a is_zero(), such that one would have to test for a type (of a return value) first.
I can do it, I just wanted to check beforehand if anybody objects.
