I would look into something like:
#include 
my_type x;
if(boost::serialization::implementation_level,
boost::serialization::level_type::not_serializable){
    ...
}
or some variation of there of such as:
#include 
namespace boost {
namespace serialization {
template<class T>
struct is_serializable {
    typedef typename
        boost::mpl::greater_than<
            boost::serialization::implementation_level,
            boost::serialization::level_type::not_serializable
        >::type
    type;
};
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.
OK - looks like you've got me there. I was hoping
that there was a cheap trick - but I guess not.
