 I use B.Range with B.Foreach closely and consider
 boost::adaptors::indexed() not so good one. I would like to use it as
 follows:
   {{{#!python
   std::vector<T> array;
   BOOST_FOREACH( boost::index_value<T&> iv, array | enumerated() )
   {
      int i = iv.index();
      T&  t = iv.value();
      ...
   }
   }}}

 I've implemented such one in my program (using indexed() as source),
 http://gitorious.org/bombono-dvd/bombono-

 dvd/blobs/master/src/mlib/range/enumerate.h and hope it will be useful for
 others too.
