It's too bad CSS doesn't allow parenthetical grouping and distributive
operations. If it did you could say this:
expr(>whatever:visible:last)
XPath seems to only support parens for boolean expressions and not for
selector grouping, so I don't think you can say this in XPath either:
//expr(/whatever:visible:last)
In any case, jQuery doesn't support parens in selectors so it's kind of
academic. But I do wonder why neither syntax allows it.
