True, but consider also that dynamic_cast has a different interface: template<class Target, class Source> Target dynamic_cast(Source); so even if we could overload it, the syntax would have been shared_ptr<Y> py; shared_ptr<X> px = dynamic_cast< shared_ptr<X> >(py); > Alternatively, it could be named boost_dynamic_cast > and put in the global namespace, where it can be overloaded as needed by > boost. This doesn't look too good if you consider the possible boost->std transition. :-) _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
