At the beginning you're kinda was against the "make" test, because there is no such thing in jQuery, and now you practically offer the same thing, to test something that does exist in jQuery but doesn't in RighJS. You should choose already what do you stand for. But anyway, if you want to test it go ahead, you know where the code is. I suppose jQuery handles virtual selectors via JavaScript and therefore there will be no serious difference in performance. I even suspect that a single additional function in the filter method in RightJS will still work faster than several internal selectors in jQuery.
