Re: [Boost-users] [serialization] Can one serialize classes based off the curiously-recursive template pattern (or any non-polymorphic base)? (was: Re: Visual Studio 2008 + Boost 1.35: runtime casting not working)

I guess for multiple inheritance, one would serialize all the  
(direct) base classes.  Do they have to be in declaration order?  And  
for a virtual base class, wouldn't _every_ derived class have to  
serialize it in its code, since a derived class wouldn't know if it's  
the final type or not?  How do you make sure the virtual base class  
gets serialized exactly once?  Do you use reference counting here, or  
make sure that multiple-serialization is safe?
