David, thank you for giving this to us to play with. As for the  
restriction you mention, I don't see any real downside to relaxing  
that. Maybe others do, and can comment on that. If it only meant that  
variables could not be used until after they are defined in the serial  
reading of the CSS, I could live with that (which would make them into  
de facto constants, I think).
