 follow code is compile error:
 {{{
 #include <boost/graph/directed_graph.hpp>

 using namespace boost;

 int main()
 {
     directed_graph<> dg(5);
     graph_traits<directed_graph<> >::vertex_descriptor
         dv = vertex(3, dg); // error!

     undirected_graph<> ug(5);
     graph_traits<undirected_graph<> >::vertex_descriptor
         uv = vertex(3, ug); // error!

     return 0;
