Sorry :-)

The way I see it is the following: Everything that is an opaque data type is a
structure. If an implementation really wants to make this opaque, use a
forward reference without data fields. This way you can only deal with the
structure as a pointer, but that might be acceptable.

As we have talloc destructors, a convention might be to simply talloc_free
such an abstract data type and have the module clean up itself.

Tridge once mentioned better syntax highlighting in editors, but I think this
hardly qualifies as a technical reason. I think it really comes down to
taste.
