-- assume the obj from last example
obj.inspect = function (self)
print("A person: " .. self.name .. " of the age " .. self.age)
end
obj.hello = function (self)
print(self.name .. ": Hello! I'm " .. self.name)
end
obj.goodbye = function (self)
print(self.name .. ": I must be going.")
end
-- now it receives the calling object as the first parameter
obj.inspect(obj) -- A person: John of age 20
obj.hello(obj) -- John: Hello! I'm John
obj.goodbye(obj) -- John: I must be going
