Using "data tables"
(Contains content from multiple discussions) Think of element.data and element:getAllData.
- variables return a referenced table
- function returns a copy
element.data.moo = "foo" -- works! element:getAllData().moo = "foo" -- doesn't work! local elementData = element.data elementData.moo = "foo2" -- works!

OOP Metatable Restructure
(Contains content from multiple discussions)
- "right now set and get functions for variables are hidden, people can't easily manipulate them", "i wanna move them to the class table".
- For example:
Element.health = { __set = setElementHealth, __get = getElementHealth }
-- lil_Toady originally suggested "set" and "get", but this could cause conflicts
-- if users assigned variables to "set" and "get" for purposes other than this
- This makes it "a bit more transparent" and will make inheritance better by applying inheritance on the class table directly
- > this will be faster and much easier for users to implement their own classes
Zombie = {...}
setmetatable ( Zombie, { __index = Ped } )
