I don't think it will be all that hard once its apparent what the problemis. (Of course that's what I always think - that's my problem)

my current thinking is to implement something like

template<class Archive, class T> common_iarchive<Archive>::move(T & dest, T & source)

which would do the assignment and update the tracking information. Then use it in the de-serializaton of all the collections.

This particular interface, if I'm not wrong, is of no use for the collections case, since the assignment is done internally by the container. At least, you need a similar facility that only does the tracking thing: template<class Archive, class T> common_iarchive<Archive>::move_track(T * dest, T * source) // no assignment While we are at it, it could be good to have something along this line for a different but related situation: sometimes it can be necessary to serialize pointers to objects which are *not* serialized themselves (i.e. they are reconstructed by some other means.) This can be achieved with something like: template<class Archive, class T> common_iarchive<Archive>::set_track(T * p) which allows the object pointed by p to be tracked (that is, pointers to it can be serialized) without attempting to load/save the object itself.
