People, are you serious about all this?

What CPU would you use to process this:

:root < a:hover { color:sisyphean; font:boulder; }

?

This simply means recalculation of styles and layout of all DOM elements 
on simple a:hover. So is my question above.

Complexity of style resolution for *single* element using
containment selector is O(n), where n is a number of DOM elements in the 
whole tree. So resolving the whole DOM against single containment rule 
is O(n*n). This will not fly.
