So, my original question stands -- it is even possible to make boost::any serializable?

I've spent a few minutes looking at boost::any and don't see any obvious way to do it in a general way. If it is possible, it would only be so by depending on or expanding upon implementation of serialization.

So, what can I suggest? Here are some very preliminary thoughts. .... template<class Archive> void my_class::load(Archive & ar, const unsigned int version){ // define which types we think we will be = m_any; boost::variant v; ar >> v; m_any = v; }

I don't think this is good in general. If it's good, then we don't need boost::any at all, we can just boost::variant. What about idea I've expressed in another email: Guess we still need a way to register every new instantiation with the serialization library. Maybe, something like this will work: template<class T> class any_value_holder { static boost::proably_not_yet_written::serialization_register< any_value_holder<T> > register_it; }; Is it possible to make this work? - Volodya
