Just a small note:

Code: Select all

item = {}
item.__index = item

function item:new(id)
   local item_object = setmetatable({}, item)

   return item_object
end

Seems that "item.__index = item" doesn't do anything at all.

You might want to check that again, the example I wrote works fine. You might have a point with separating the "interface" as you call it so that an object doesn't have the new method, but as it stands the code works exactly as intended lol.

It's the same thing, a table with a property __index with value item, so yes it's the same in both cases.
