Comment (by Geurt Vos <geurt.vos@…>):

 this works:

   boost::unordered_map<int, int> m = boost::assign::map_list_of(1, 1)(2,
 2);

 this doesn't:

   boost::unordered_map<int, int> m; [[BR]]
   m = boost::assign::map_list_of(1, 1)(2, 2);

 with the follow errors:

 boost::unordered::unordered_map<int, int>]’ is private [[BR]]
