Re: QSA, the problem with ":scope", and naming

Overall, I wholeheartedly support the proposal.

I don't really see the benefit of allowing starting with a combinator. I
think it's a rare case that you actually care about the scope element and in
those cases, using :scope is fine. Instead of element.findAll("> div >
.thinger"), you use element.findAll(":scope > div > .thinger"). That said, I
don't object to considering the :scope implied if the selector starts with a
combinator.

Can we define it as a sequence of selectors and be done with it? That way it
can be defined as using the same parsing as CSS.
