Ah, got it.

Using a bare "var-foo" keyword for variables wouldn't work unless we
permanently reserved all keywords starting with "var-".  Possibly, but
not ideal.  This also suffers from the same problem that using "$foo"
does - if it's a single token, I can't expand its powers later, such
as adding a default to be used if the var is undefined/invalid.

There's an issue in the draft already about aligning the definition
and use syntax, though the suggestion there is to use "var(foo):
blue;".
