I'll address the rest of the issues in this thread later this week, but
I just wanted to clarify this one issue now.

* Combinator-rooted Queries
I read about some prior discussion concerning this (especially in
relation to DOMElement.querySelectorAll-style queries). This is an
important part of most libraries, as it stands. Maciej's proposed
solution of using :root to allow for front-leading combinators is
perfectly acceptable to me (where :root is made equivalent to the
element, not the document element).
// jQuery $("#foo").find("> span");
// DOM document.getElementById("foo").querySelectorAll(":root >
span")
This is something that a library can easily detect and inject.
The current plan is to eventually try and introduce a :scope
pseudo-class for that purpose. The Selectors spec clearly defines :root
as matching "the root of the document", and redefining :root for use in
these APIs alone doesn't seem like a good idea.
