| 100682 [cpine@he lo ] Actually, since 0 is an immediate value (like nil and false), it could be tested just as easily (as I understand it). I would guess that the reason has more to do with elegance and simplicity. In any case, aside from the "C does it that way" camp (whom we are obviously not catering to), why should 0 or any number be false? (Why should "" or any string be false? Why should  or any array be false?) Well, they aren't.
