As mentioned, I never remember which kind of "positivity" is used where, whereas (> 0 x) and (>= 0 x) are 100% unambiguous. > (The same logic for `zerop', by the way.) I find (= 0 x) to work just as well, but at least `zerop' doesn't suffer from plusp's ambiguity, so I'm OK with zerop (tho after having had to work to make it as efficient as (= 0 x), I started to stay away from it).
