It's bizarre:

     typedef Prism                                                    prism_type;
     typedef typename std::map<face_type const*, prism_type>          prism_map;
     typedef typename prism_map::iterator                    base_prism_iterator;
     typedef          map_data_iterator<base_prism_iterator> prism_iterator;

     bool debug_verify( prism_map & prisms )
     {
       for ( prism_iterator prism = prisms.begin(); prism!=prisms.end(); ++prism)

     }

Once again, thanks alot,
