Even cooler:

    (defun make-match-list (num string)
      (let ((match (match-string num string)))
        (if match (cons match (make-match-list (1+ num) string) ))))

    (defun match-data-format (data match format-str)
        (string-match match data)
        (eval `(message format-str ,@(make-match-list 1 data) ))))

     "header is: %s\nname is: %s\ne-mail is: %s") ; eval me
