i've been using (but for some reason haven't commited) this for
openmcl:

(defimplementation toggle-trace (spec)
  "We currently ignore just about everything."
  (ecase (car spec)
    (setf
     (ccl::%trace spec))
    (:defmethod
     (ccl::%trace (second spec)))
    (:defgeneric
     (ccl::%trace (second spec)))
    (:call
     (toggle-trace (third spec)))
    ;; mb: FIXME: shouldn't we warn that we're not doing anything for
    ;; these two?
    (:labels nil)
    (:flet nil))
  t)

personally i think it's cleaner to just implementation toggle-trace
admititng that we don't actually do much.
