Even though rfc822 messages are exactly like any other GMimeObject,
there appears to be no way to return the message as a GMimeObject.
This limits what can be done with the message parts.  Having the
message available as a GMimeObject would:

* allow for retrieving *all* headers from the rfc822 message in a
  message/rfc822 part (using eg g_mime_object_get_header), not just
  the few available with the GMimeMessage method.

* allow for outputting the full raw message with
  g_mime_object_write_to_stream ().

* allow for totally symmetric handling of all parts (see the example
  recursive function below).

I suggest the function be defined as:

GMimeObject * g_mime_message_part_get_object (GMimeMessagePart *part);

Thanks, and please let me know if you have any questions.

static void
do_part (GMimeObject *part)
{
  /* do stuff on part headers */
  if (GMIME_IS_MULTIPART (part)) {
    GMimeMultipart *multipart = GMIME_MULTIPART (part);
    int i;
    for (i = 0; i < g_mime_multipart_get_count (multipart); i++)
      do_part (g_mime_multipart_get_part (multipart, i));
  }
  else if (GMIME_IS_MESSAGE_PART (part)) {
    do_part (g_mime_message_part_get_object (GMIME_MESSAGE_PART (part)));
  }
  else {
    /* do stuff on part content */
  }
}
