Hey,
Here's an autoregistering serializable any, I think it qualifies as hacky and suboptimal. Of course the typeid(T).name() strings aren't portable,
if you use serialization/extended_type_info, instead of typeid(T)name() you can use the strings used by BOOST_CLASS_EXPORT which are portable.
Hm, I don't quite follow... BOOST_CLASS_EXPORT(T) just associates "T" with typename T. Maybe one could cobble together something like BOOST_ANY_EXPORT(U) which would expand to something like BOOST_CLASS_EXPORT_GUID(boost::any::holder<U>, "boost_any_holder_" BOOST_PP_STRINGIZE(U)) But one of the OP's requirements was that a list of instantiations of anys not be necessary. Do we want to toss that requirement in favor of moving closer to something that could actually go into the library... or what am I missing? -t
