Very interesting. As far as use cases, one might take a look at extended_type_info in the serialization library. It seems related to this.
I don't see a connection between boost::variant and extended_type_info. Isn't extended_type_info designed to handle any type? This is unlike boost::variant, which is just a type-safe union.
I agree. And, some simpler templating techniques may be used to map the current helt type discriminator to the (C++) type, thus dispatching calls by other means than what is typically referred to as 'visitation'. (I still fail to appreciate the usefulness of those compile-time static strings. I find them rather ugly...) Regards, Stefan -- ...ich hab' noch einen Koffer in Berlin...
