--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Thanks. And again with no library dependency:

template<bool, typename = void> struct enable_if { };
template<typename T> struct enable_if<true, T> { using type = T; };

template<typename> struct trait { static constexpr bool value = false; };

template<typename Key>
struct map {
    template<typename Pair, typename = typename
enable_if<trait<Pair>::value>::type>
        void insert(void * pos, Pair&& x);

    template<typename Iterator>
        void insert(Iterator first, Iterator last);
};

template<typename IdType>
struct map_type_to_map : map<IdType> {
    void add() {
        void * ptr = 0;
        map<int> current_values;
        current_values.insert(ptr, ptr);
    }
};
