Hm, yes. You're afraid they will change the structure of that namespace from under our feet without even putting it in a changelog.
Given that possibility, might it not be better to put it in namespace std anyway...
Perhaps they should offer us a real solution in the next version?
'They' are open to any suggestions ;)

I suggested that boost should actually only print adapters to the stream. The default behavior would be to template<class T> struct repr_type{ typedef T type; T make(T value) {return value;} }; template<class T> typename repr_type<T>::type repr(T& value) { return repr_type<T>::make(value); } Then to print log messages: stream << repr<>(obj1) << repr<>(obj2); and to customize output when overloading operator << is not possible, you can use template specialization. template<class T> struct repr_type<std::vector<T> > {...} --John
