This would mean that if you had one "root" ruleset (e.g. "html") then 
current CSS parsers would all ignore your entire style sheet (except for any 
declarations for "html"). Not really graceful degradation that all CSS 
updates strive for.

However, there's nothing stopping you from using your custom syntax and then 
have a script that converts it to real CSS. You can add things like 
constants and more fancy selectors, too, without adding any burden to 
implementors or breaking backwards compatibility.

FWIW, this can most probably be written as:

   #menu ul ul ul {}

Selectors aren't that hard to understand IMHO, and introducing yet another 
way to do it would only confuse matters more, I believe.

And there's no reason you can't use the current syntax as a "tree". Just put 
the rulesets in the correct order (as if you had a tree) and indent them 
appropriately. I do this because it makes for easier maintanence.

I don't see how it forces better design at all. You can still make your 
style sheets unorganized. Espeially since the old syntax still has to work.

Use gzip compression if you're worried about file size.
