I see I was reading too deeply into the syntax. Realizing we've already enabled the self-refining behavior in :not based on tag names (and more) makes it clear. Also makes it clear about why a change for :not would be handy as well to match the syntax of any.

Sorry for the randomization.

> I'm using the above for reference. I'm a little bit concerned here. It seems the standard rules of selectors are broken by the syntax. Namely that a simple selector consisting of a pseudo class :foo is actually the selector *|*:foo, but the example notes that the replacement for :-moz-any is in place and is no longer a "tag rule". This is creative, but if we plan on doing this we should introduce a concept into the grammar which is not a pseudo-class that allows you to root the front of a selector using a new special character so you can disambiguate from a standard tag rule immediately.

I don't see what's broken here.  :any(a,b) is still identical to *|*:any(a,b).  The fact that you're specializing the tag selector more than once is a minor detail; the same applies to a:any(a,b).  (The fact that a rule ending in :-moz-any() doesn't fall into the "tag bucket" is just an implementation detail, as the blog post notes.)
