Sure, but if we don't have a way to reliably distinguish unions from classes, we're out of luck because there's no way to make is_polymorphic do something special for unions. We could put in the test for is_union and then ask users to specialize is_union<U> for their unions U until they get compiler support for that type trait. best-i-can-do-ly y'rs, Dave -- Dave Abrahams Boost Consulting www.boost-consulting.com _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
