The following code used to work, but no longer does.

    typedef boost::adjacency_list<> G;
    typedef boost::graph_traits<G>::edge_descriptor E;
    G graph;
    std::vector<E> spanning_tree;
      , std::back_inserter(spanning_tree)

Somehow the concept checking became too restrictive,
and type E is now expected to be Assignable, which
currently doesn't seem to be the case.

Any fixes or workarounds?
