Agreed. For example, I never can remember the order of all template
arguments to adjacency_list, and declaration of properties. Maybe, some
combination of "named template parameters" and mpl::list would help:

   adjacency_list< graph_config<
        vertex_property_t, mpl::list<vertex_index_t, unsigned,
                                     vertex_name_t, std::string>,
        edge_property_t, mpl::list<edge_weight_t, float> > > graph;

The "associative_list" that was posted some time ago probably can be used to
implement this syntax.

(BTW, shouldn't we move this conversation to the main mailing list. After
all, we're not talking how to use existing interface, but how it can be
improved).
