  Roberto & Co. probably did that to avoid this:

        waiting  = {}
        longtime = {}

        setmetatable(waiting  , { __index = longtime} )
        setmetatable(longtime , { __index = waiting } )

        waiting['for'] = 'Godot'
It's technically unavoidable but it does have a check to avoid infinite loop in __index
