The following pieces of code so the same.

Hmm, I do not understand why that is bad :3 I'm not sure why you would do that, but if that is your intention... you can still a['read'] and a['write'] = 'to' the table `a', you just iterate over something else. It would be the same as if you had done: setmetatable(a, { __pairs = function () return pairs(tbl) end })
