While this isn't much relevant to C as such, this is the newsgroup I saw the above in, and I feel obliged to point out that Lisp implementations need not be large, nor slow, nor perform garbage collection in a disruptive way. Incremental garbage collection techniques have been published for many years now (I think I saw one in CACM not long before it turned into a yuppie magazine). There are even special hardware architectures (Lisp machines) for people who are heavily into Lisp-based applications.
