Dear list,

I'm trying to write serialization code for Boost.System's error_codes, 
however I'm having trouble to serialize/deserialize an error_category, which 
are polymorphic singleton objects.

I guess when saving, type information needs to be stored, like with 
polymorphic pointers? When loading, a global function 
(get_generic_category(), get_system_category(), etc.) could be used to 
obtain a reference to the singleton object. Is there any way to use the 
exported type information in such way that a reference to the correct 
singleton is obtained?

Any suggestions on how to approach this?

Thanks in advance,
Kind regards,
