Seems pretty limited to me. Is this any better than a single-pass 
precompiler?

In addition, you'll run into problems because you decided to use CSS 
selector as a key to reference to. For example:

serif, fantasy /* elements 'serif' and 'fantasy' */
{
 font: "Arial Unicode MS" 1em;
}

fantasy.font /* special class here */
{
 font: "Garamond" 1em;
}

.myspecialclass
{
 font: serif, fantasy.font; /* is this replaced? */
}

Or

p
{
 color: blue;
}

html:nth-of-type(1) > head + body div > table td > p
{
 color: red;
}

html:nth-of-type(1) > head + body div > table td > ul > li
{
 color: html:nth-of-type(1) > head + body div > table td > p.color; 
/* is this supposed to work to get red instead of blue? */
}

It may be pretty easy to implement but if it has no power over a 
single-pass precompiler, it's not worth it.
