empty array advice

[OnlyPiglet]

decode empty array string and encode the lua table into empty array automaticly.

I add the code in this place in the file lua_cjson.c ,it works.

    /* Handle empty arrays */
    if (token.type == T_ARR_END) {
        lua_pushlightuserdata(l, json_lightudata_mask(&json_empty_array));  //added
        lua_rawget(l, LUA_REGISTRYINDEX);          //added
        lua_setmetatable(l, -2);             //added
        json_decode_ascend(json);
        return;
    }

I. think the off diffience between after_decoded_empty_array table and raw lua empty table is that the after_decoded_empty_array has a empty metadata table. yes?
