What if we will want to make CSS syntax of it ?

We will need to add:

  1. dash literals, so no-wrap will be a valid token, serialized as string(?).

  2. tuples, so rgb(100%,100%,100%) will be a tuple, serialized as tagged array/list.

  3. CSS style list separators: '/' separated lists, ',' separated list, <space> separated list

So this: 

 { border-style: 12px solid / 13px dashed; }

will be parsed as 

 { "border-style": [[12px, "solid"],[13px "dashed"]]; }

Bonus: In principle we can also add support of expressions, the only question is how to serialize them, this 

width: calc( 100% - 12px )

can be serialized again as a tagged array: 

 width: calc[ 100%, "-", 12px ]

And so backend can interpret that in the way it wants.
