I agree that zero and false are generally equivalent, except possibly in the case of unix shell scripts where it gets messy. It's arguably unsafe to ever cast true to a number or enumeration, and possibly the best behaviour would be to ensure that the compiler always handled for b := false to not false do and for b := not false to false do the same.
Should obviously have read b := not false to true do Need more caffeine. The salient point is that both give you full coverage of an enumerated type, so it's reasonable to expect every value to be iterated although the order might be undefined.
