I meant "wrong" as in "I would ideally flag this in review for being weird and confusing". Of course there are many reasonable cases where you might pass an integer "foo" rather than explicitly booleanizing it with "!!foo". So I do agree it's a real potential problem (and I'm sufficiently convinced that we should avoid an "int" fallback if we can). -Peff
