I haven't been following this discussion closely, so I'm probably wrong, but that statement doesn't sound right to me. As far as I'm aware, the declarative layer is just a convenience for setting up Tables and mapped classes at the same time. The end result is exactly the same as if you created the tables and classes in the traditional way. I would be very surprised if the above expression didn't work. You can get the mapper for a mapped class or object using the "class_mapper" and "object_mapper" functions.
