Hmm, perhaps I misunderstood---I thought you were talking about creating duplicates via `push` etc., but it sounds like you are worried about duplicates in the result of `queryAll`? If so, then yes, I agree there should not be duplicates in that result. It may be a mismatch between my "polyfill" (which was meant to be more illustrative than anything) versus the actual spec.
