Does it really make sense to make a special case just for media queries? 
As far as I understand the CSS specs until now things like @media, 
!imporant, color, red are *all* IDENTs which may contain CSS escapes. If 
I understand the proposition of this thread right it is suggested to 
make a special exception just for keyword "all" "print" etc in this 
case? Does it not make problems for existing implementations which use 
something like

	@media all {...}
	@media a\ll {...}
	@media \61 ll {...}

as equivalent?


Sorry if I misunderstand the issue but I just saw the whole thread and 
am a bit out of context...
