The reason it got dropped is that some people (including Tab) do believe we 
should reserve $ for mixins and other preprocessor-like operations which may 
potentially be added to the language at some point (e.g. futuristic things 
like:

    @define apply-2d-transform(initial-scale, initial-rotation, ...) {
        ...
        my-transform-scaling: $initial-scale;
        my-transform-rotation: $initial-rotation;
        ...
        transform:
            scale(get(my-transform-scaling))
            rotate(get(my-transform-rotation))
            translate(get(my-transform-translation));
        will-change[]:
            transform;
    }

    .some-element {
        $apply-2d-transform(...);
        transition[]: transform 0.5s ease-in-out;
    }

    .some-element:hover {
        my-transform-scale: 1.1;
    }

but this syntax was just made for this example, final milage may look 
completely different and/or offer different features)
