-------- Jose, is that OO enough?
-------- If not, here's the trick:

actor = {}
local function actor_new ()
   local self = {}

   -- public:
   function self.update ()
      print("Actor::update")
   end

   return self
end
setmetatable (actor, {__call = actor_new})

soldier = {}
local function soldier_new ()
   local self = actor ()

   -- private:
   local actor_update = self.update

   -- public:
   function self.update ()
      actor_update ()
      print("Soldier::update")
   end

   return self
end
setmetatable (soldier, {__call = soldier_new})

local soldier1 = soldier ()
soldier1.update ()
