"I asserted that you could define the "most powerful language in the world" in "a page of code." I had orignally made the boast because McCarthy's self-describing LISP interpreter was written in itself. It was about "a page", and as far as power goes, LISP was the whole nine-yards for functional languages." --- Alan Kay in http://gagne.homedns.org/~tgagne/contrib/EarlyHistoryST.html
