Yes. :-)
To see if you don't use a previously saved value, you can check against
the message id (which is unique per process).
e.g.:

 /* set var */
 saved_id=msg->id;
 saved_value= ...;

 /* check val */

 if (saved_id==msg_id){
    return f(saved_value);
 }else{ /* no value was saved for this message, use the default one */
    return f(default_value);
 }
