Not many, but even so, this is never the right question to ask. That question would be: what programs are written in <LANGUAGE> that couldn't benefit from being rewritten in another language? And most often, the answer to that question is none. Because languages matter a lot less than language fanatics want you to think. As for Lisp, I used to be a total fan until I realize the importance of a sound static type system, and now I will never go back. Lisp will never go anywhere because this is the 21st century and we know now that static type systems are an absolute requirement for modern programming.
