If you mean that a noun phrase must have a noun in it, where nouns and noun phrases are capable of filling the same slot in a sentence, then I point to French, where nouns cannot serve the purposes of noun phrases (a raw noun without a determiner is ungrammatical).

Yes, absolutely. But if the recursive invocation is at the *end* of the procedure, then it's a special case with no stack required. Just jump back to the beginning of the procedure and do it again. Thus, X <- X0, X <- Y X does not require recursion; it comes out loop: if x0 found, then success; if y not found, then failure; repeat -- John Cowan http://www.ccil.org/~cowan cowan@ccil.org Please leave your values | Check your assumptions.
