   accessing an luabind class member from c++
  hi,i'm new to lua/luabind and i would like to access a member from an luabind class.for example, my luabind class looks like this:class 'Channel'function Channel:__init()self.id = 33--return selfendhow can i access the id field from c++ ? i guess i should use "luabind::object" but i am stuck on which method/way to get access to the class member.thanks in advance!   
  If you get your channel object into a luabind::object, you can just do something like this:// (or however you're getting your luabind object)luabind::object o = luabind::globals(state)["channel_thingy"]int id;if (luabind::type(o["id"]) == LUA_TNUMBER) {    id = luabind::object_cast<int>(o["id"]);}Check out the luabind docs chapter on iterators too.
