The part about lisp being primitive was rather silly. Many languages don't have anything close to what Lisp has in its macro system, not even other functional languages, even in those languages with temperating systems. Perhaps Perl 6 comes close (I haven't had the chance to use p6 macros yet) but to say that lisp is 'primitive' is rubbish, unless you're going to claim that case insensitivity is enough to declare a language primitive.
