overriding method of a single object and calls its metatable method ?

[gary ng <garyng2000@...>]

Hi,

Given the following construct(as mentioned in PIL)

A={}

function A:new(o)
 local o=o or {}
 setmetatable(o,self)
 self.__index = self
end

function A:foo()
 print("foo of A")
end

a=A:new()

how can I easily define a method a.foo which is
equivalent to this :

function a.foo()
 a.super.foo()
 print("foo of a")
end

which has this output :

foo of A
foo of a
