The use of `message' that you just showed doesn't
do that.  The use of `message' that I spoke of does
do it - use `message' in the binding forms:

(let* ((fred      42)
       (_IGNORED  (setq fred  'nope-24))
       (_NADA     (message "FRED: %S" fred))
       ;; ...
       (_NADA     (message "FRED: %S, "FROG: %S" fred frog))
       ;; ...
       )
  ;; ...
  )
