The default serialization traits are such that pointers to primitive types
are set to not-serializable.

Suppose you set the implementation_level<long> to object serializable and
serialize a pointer to a long. This well mean that all serialized longs
have to be tracked. Do you want something like this to happen? Its possible
to serialize a pointer to primitive - I just can't imagine a case where one
would want to do because of the side effects it would cause. That's why I
recommend wrapping the primitive in its own type so that you don't create a
lot of unexpected/undesired side-effects. Look at strong typedef for a
simple cheap automatic wrapper.
