Yes, I remember you asked for support for objects without ids some time
ago. I did more thinking on this feature and I believe we can probably
support this. Such objects, however, will have a number of limitations,
biggest of which is that you won't be able to update such objects using
the database::update() function. This is probably not an issue in your
case, but I just want to confirm.
Essentially, one will be able to persist such objects using the persist()
function, load them using query() (load()/find() will not be supported)
and delete such objects using erase_query() (again, normal erase() will
be unavailable). Let me know if you see any problems with these
