Explaining why, {}=={} is not doing anything special to compare values in tables. What it does is create two completely different tables and compare their pointers. Since they are exactly two different tables, their pointers are different and this results in false. If you want to check if the table is empty, the most basic way is to call next(wait) and see if it returns nil.
