People making smart points are really annoying... !-) wrt/ to the "subtle bug" point, MHO is that a better solution could be to have iterators/generators implement __nonzero__ the same way numpy arrays do. It may not be a very strong argument, but I actually like the fact that empty sequences eval to false just like numeric zeros and None... -- http://mail.python.org/mailman/listinfo/python-list
