What if your existing clients might have
(defun paul-callback (computed-data &optional cached)
...)
where they make calls to `paul-callback' themselves with the extra
argument? It's fair to call this "abstruse" (maybe most/all clients
just use a lambda), but it might also make you think about providing
another callback interface.
