I think "if f is None:" and even more "if callable(f):" are
better ways to express this test -- explicit is better than
implicit.  However, if this (inferior) expression is indeed
widespread, then we can't break it until Python 3000 (well,
we COULD start giving warnings about it, etc, etc, but it's
unlikely that this can happen).
