the table is not copy~~ about 30log

[zorfmorf]

The problem is that you are assigning a new table to Obj.tab during class creation. This means that all your tables that inherit from Obj will share the same tab table. In your case you want to use the init method provied by 30log as described here.

> class = require '30log'
> Obj = class("Obj")
> function Obj:init() self.tab = {} end
> o1 = Obj:new()
> o2 = Obj:new()
> o1.tab.x = "BuiBuiBui"
> print(o1.tab.x)
BuiBuiBui
> print(o2.tab.x)
nil
> 

And what's up with the "var" definition? Did you replace the "local" keyword?

Although @zorfmorf provided a nice solution, the latest commit should provide some fix to the code.
Try this new one, it should be working nicely.

local Obj = class("Obj", {
tab = {}
})

local o1 = Obj:new()
local o2 = Obj:new()
o2.tab.x = "BiuBiuBiu"

print(o1.tab.x) -- outputs nil
print(o2.tab.x) -- outputs BiuBiuBiu

Let me know if everything is okay with commit 8a8ae92. If so, i'll flag with new bugfix version tag.
Thanks.
