thanks for pointing out my error.  how do i get around it?  i am not a
C++ expert but how do i serialize the reference as a pointer?  i tried
various castings to no avail.  by the way, what i wrote was copied
nearly verbatim from the documentation

template<class Archive>
inline void save_construct_data(
    Archive & ar, const my_class * t, const unsigned int file_version
){
    // save data required to construct instance
    ar << t.member1;
    // serialize reference to object as a pointer
    ar << & t.member2;
}

which seems like it wouldn't compile, since t is a pointer so
t.member2 doesn't seem right.

thanks, and best regards,
ben
