why?
typedef … K;
typedef std::map<k , HANDLE> map_type;
map_type map_;
…
std::for_each(map_.begin(), map_.end(),
boost::bind(&map_type::value_type::second, _1)); // this works
std::for_each(map_.begin(), map_.end(),
boost::bind(WSACloseEvent,
boost::bind(&map_type::value_type::second, _1)));
// this barfs inside boost::bind … incomplete type
