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
