+1, but with two remarks:

- Allowing function notation to property names can be useful to support 
list-valued properties, even if it isn't the only option to do so.

    transform(zoom): scale(2);

- I don't think you're right to say that using plain var-keyword as a value 
makes it impossible to add options like custom variable inheritance or 
default values. If you also register all function starting with var- as a 
prefix, I think you're okay. You just need a lookup for an opening 
parenthese after the identifier.

    .a    {     var-xxx: value;     }

    .a    {     var-parent-xxx: var-inherit(var-xxx);     }

    .a    {     property: var-default(var-xxx, auto);     }
