I guess I don't understand what a head is. 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). Can you spell this out a little more?

Ah, I understand *your* point now.

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
