Let's assume for a second that it didn't create parsing ambiguities.
Would you really prefer:
div
border: width solid blue
over:
div
border: $width solid blue
I think the latter is much more clear from a reader's perspective.
And without the prefix we could also do horrible things like this:
solid = dashed;
blue = #f00;
width = 1px;
div
border: width solid blue
which would emit:
div{ border: 1px dashed red; }
In a programming language, you're working with variables all the time. They
are the most common thing you work with and so it makes sense that you'd
optimize the syntax around them, but in sass you're building styles first
and variables are secondary -- as such, I feel quite strongly they should be
easily identifiable as special.
Anyways, Nathan has already finished coding all this up and it's on the scss
branch. Thanks to everyone for your input. The use of ! as a variable prefix
will be deprecated in sass 3.
