I'd like to do something like: typedef typename boost::mpl::if_< typename base::is_container<T>::type, typename T::element_type, T>::type ElementType_; such that T may be a primitive type. The above doesn't work since, for example, there's no such thing as int::element_type. Is there a simple way (eg don't have to do template specialization for all container types) to do the above? Thanks, Noel
Try mpl::eval_if
