    Essentially:

       (let ((env (vector 0)))
	 (curry env (lambda (env) (aset env 0 (+ (aref env 0) 1)))))

    [of course, `env' is not visible to the user code]

The word "essentially" means that this isn't really
the answer to the question.  What precisely are the Lisp
objects produced?

Why use `curry' for this at all, rather than implementing
a `closure' funcvec type?
