Hi Lachlan,

Have you considered handling these queries by passing an option
to querySelector that scopes the selector to the context node?
(Or in the case of HTML5 scoped style, defining a syntax for the
style element that does the same.) What are the advantages of
doing this with a pseudo-class instead of that approach?
