RE: 'legal' / 'important' and cascading order

This issue is something that I mentioned to Hakon last week - it's kind
of a pain to have to split important/legal weighted properties out of
the declaration at parse time.  What would people think about putting
the important/legal moniker on the entire declaration instead of a
property declaration, e.g.:

H1.foo !important { color:red; font-style: italic }

This would seem to simplify the management of important and legal
declarations significantly, at least in my opinion.  Anyone else?
