I played around with that a little, but it looks like for that to work I'd need to do something like

BOOST_CLASS_IMPLEMENTATION(my_class, boost::serialization::not_serializable)

for each type that was not serializable... am I missing something? In my experiment it seems like


resolves to object_class_info unless I use the BOOST_CLASS_IMPLEMENTATION. That's akin to manually marking the types, which I'd like to avoid if possible.
