Hi, Do we have serialization support for boost::any? If not, how is it possible to serialize boost::any?
Good question. Robert, is it possible to place BOOST_CLASS_EXPORT inside class definition, so that I can write something like that:
class any_base {}; template<class T> class any_value_holder : public any_base { ....... BOOST_CLASS_EXPORT(any_value_holder); };
and have BOOST_CLASS_EXPORT run for each instantiation of any_value_holder?

This would tie the GUID "any_value_holder" to multiple types any_value_holder<T> so it wouldn't be unique any more. This is another manifestation of the general problem of retreiving an external string from a typename. type_info does this but in a non-portable way. Of course you know this as you rasied this issue in the first place. Much fame and fortune will accrue to he who creates the function template<typename T> char * guid() which returns a unique char string in a platform independent way. Good Luck Robert Ramey
