The suggestion (#28, "Symbolic Constants") is rather vague.  I find the example

	@define orange = #faa;

of dubious value: it just defines a *value* in a declaration.  What good does
that really do, anyway?

Chris pointed out that the proposal is to provide a maintainability convenience.
Many of us are repeatedly declaring the same set of styles over and over.  You
*could* use grouping, followed by overriding/extending,

	h1, h2, h3 { styles common to h1, h2, h3 }
	h1 { overrides/extends common styles }
	h1 { overrides/extends common styles }
	h1 { overrides/extends common styles }

but it's a pain, and inefficient to boot, especially if you're overriding parts
of styles already declared.

I "voted" in favor of #28, but please discount it if the purpose is just to
declare single *values* -- I don't see the value :).  If OTOH it is to define
one or more *declarations*, I think it will be useful to many of us who
hand-code our CSS and don't use or have access to server-side magic.
