This is overblown. The lisp is not "rendered", it is executed. Any language that can implement a recursive-descent parser/generator could be the basis for this -- it does not require lisp or lisp macros. Think about what a render would have to do, and you realize that the model of using embedded rewrite rules (macros) might be slightly more convenient, but not a really a distinct advantage over executing code which renders or outputs instructions to render later. The problem is most definitely not that you have to output an intermediate language, the problem is that HTML/CSS sucks. It is originally designed around presenting static text documents, and the committees involved were not smart enough to figure out a way to depart from that over a decade ago when pixels became important to the web.
