// in this case, indication that an object is tracked is
// not stored in the archive itself - see level == object_serializable
// but rather the existence of the operation ar >> T * is used to
// infer that an object of this type should be tracked. So, if
// you save via a pointer but don't load via a pointer the operation
// will fail on load without given any valid reason for the failure.
