Comment Editing changed the question, unfortunately (Score 2) 108
I'm glad this story got posted and sxc is getting some press, but the real question I asked was:
It is unknown exactly what power might come about from this combination of low level processing with high level code generation. Can you think of any possible uses?
The idea of using pre-processors to generate C code is not new to programming; but the usage of the full power of Common Lisp in such a natural way is up to the question.
