Passing classes by ref to function is broken

I think it can be fixed using something like this:

template <typename TRef>
struct lua_type_traits<
    TRef, typename traits::enable_if<
              traits::is_lvalue_reference<TRef>::value &&
              !traits::is_function<typename traits::remove_reference<TRef>::type>::value &&
              !traits::is_const_reference<TRef>::value>::type> {

    typedef typename traits::remove_reference<TRef>::type T;
    typedef void Registerable;

    typedef T &get_type;
    typedef T &push_type;

    static bool strictCheckType(lua_State *l, int index) {
        return object_wrapper(l, index, metatableName<T>()) != nullptr;
    }

    static bool checkType(lua_State *l, int index) {
        int type = lua_type(l, index);
        if (type == LUA_TLIGHTUSERDATA) {
            return true;
        }
        return object_wrapper(l, index, metatableName<T>()) != nullptr;
    }

    static get_type get(lua_State *l, int index) {
        return *get_pointer(l, index, types::typetag<T>());
    }

    static int push(lua_State *l, push_type v) {
        if (!available_metatable<T>(l)) {
            lua_pushlightuserdata(l, &v);
        } else {
            typedef ObjectPointerWrapper<T> wrapper_type;
            void *storage = lua_newuserdata(l, sizeof(wrapper_type));
            new (storage) wrapper_type(&v);
            class_userdata::setmetatable<T>(l);
        }
        return 1;
    }
};

In 4c19986 you forget about LUA_TLIGHTUSERDATA I think.
