It breaks, or at least deteriorates, one kind of progressive
rendering: the display of documents as style sheets are loaded. I
understand that WebKit doesn't have this problem as you wait until all
style sheets are loaded (isn't there a timeout?). For browsers that
support this kind of progressive rendering, the proposal will have
adverse effects.

I still think variables could be a good idea, though -- just not
global variables.
