Query: modern C--

Interesting book but dont' call it modern C++ design. GoF can call their book Modern Design, Mr. Stepanov can call his library Modern Design, Mr Meyers can call his books Modern Design, but this book has nothing to do with Modern Design. Either it is an old technique, wrapped in template implementation or some cumbursome code which is not applicable in real life.
