Milestone:  To Be Determined                     |   Component:  range     
  Version:  Boost 1.52.0                         |    Severity:  Cosmetic  
 Keywords:  usability                            |  
-------------------------------------------------+--------------------------
 The Graph library uses std::pair to pass ranges and this allows a nice
 pattern to use old-fashioned for-loops:

     Graph g;
     boost::graph_traits<Graph>::vertex_iterator b, e;
     for(boost::tie(b, e) = vertices(g); b != e; ++b) {

     }

 This works without any modifications with pair.

 The functionality would be great for all ranges as it provides users
 that don't want to use Boost.Range algorithms with a simple way to use
 their preferred style or algorithms from std.
