I have found wrapping to be the only viable way to deal with large, heterogeneous systems built atop many libraries from disparate sources which cannot be modified to integrate into a unified exception hierarchy. I agree that the ability to augment exceptions is much cleaner, but when the "original" exception isn't a boost::exception, I need a clean way to bridge it into the world of boost::exceptions.

Anyway, std::nested_exception looks pretty trivial to implement given the bits that already exist in Boost.Exception. Would you be open to a patch providing an implementation?
