I like your answer much better than mine.  I did
class Traits
{
public:
Traits_record *Record(void) {return NULL;}

// The rest of your class definition
} ;

template <class X, class R>
int Store(X *x, R *r) {
   R record;
   record << *x;
...
}
template <class X>
int Store(X *x) {
   return Store(x,x->Record());
}

Not only ugly, difficult to understand, but jumps around when tracing a call
with a debugger.  However, it does work!
