See the code I sent -- it had an example of `curry' being the
operation that creates the curried function given some arguments.  The
you get

  (curry +) == +
  (curry + 1) == (lambda xs (apply + 1 xs))
  (curry + 1 2) == (lambda xs (apply + 1 2 xs))

and you can use multiple `curry's to add more levels.  This seems like
the only reasonable approach for arity-at-least-0 functions.
