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

boost::serialization::implementation_level<A>::type::value

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.

Thanks
