I'll admit to being dense here.. could you explain the member template
technique further, or provide a reference that I could read? How does this
help?

4) Avoid the issue completely and avoid the restriction on using only
vector by using member templates:
        class B
        {
        public:
                template<typename iterator>
                  void f(iterator begin, iterator end);
                ...
        };
