cItem: Store custom data

[NiLSPACE]

Wouldn't something like this work?:

local g_ItemData = {}

function cItem:SaveData(key, data)
	local storage = g_ItemData[self] or {}
	storage[key] = data;
	g_ItemData[self] = storage
end


function cItem:GetData(key)
	return (g_ItemData[self] or {})[key]
end

Or would it have the same problem as the third option?
