I also realized that after trying to implement user_type/user_data and I
agree that haveing after, swapped and object tags is a much better mapping
to what you can do using signal connection mechanism.

The only use case it doesn't cover is a way to send in a string or an
integer (with GPOINTER_TO_INT), as Morten mentioned in this thread.
