Well, it may be a little less clear and verbose as an explicit comparison, it's hardly a hack, or kludgy. It's clearly allowed by the language, and competent CF programmers will easily understand it. Some languages allow implicit casting of integers as Booleans, others don't. Would you also categorize short-circuit evaluation as a kludgy hack because you can't do it in some languages? I agree that an explicit comparison is slightly easier to understand, and therefore is at least as good as an implicit comparison, but the difference is marginal at best. But at this point, we might as well be arguing about how many angels can dance on the head of a pin.
