;; I don't think we should print the forms inside lists, etc.
;; I think this is better:
;; If the top-level form yields a primitive or an operation application:
;;   print it or whatever.
;; If it yields another kind of value (list of primitives, for example),
;; I don't think we should send them to the backend...
;; It can be an intermediate step in an algorithm the user may be testing...
