Comment (by c_crickmar <chris@…>):

 The value_type would have to be translated from std::pair<Key, T*> to
 std::pair<Key, T> which couldn't be done without copying T. I suppose a
 reference wrapper could be used but then the value type is std::pair<Key,
 boost::reference_wrapper<T> > which I don't think is an improvement.
