overriding instance method with module, ultimate solution

cooks.rb

module Prepending
  def append_features(base)
    prepend = self
    base.extend Module.new { define_method(:new) { |*args,&block| super(*args,&block).extend(prepend) }}
  end
end

module CanCook

  extend Prepending

  def bake(food_name)
    "I'm baking the #{food_name}!"
  end

end

class Programmer
  def bake(food_name)
    "I don't know how to bake #{food_name} :("
  end
end


class Programmer
  include CanCook
end

Mario = Programmer.new
Mario.bake("tortillas") #=> I'm baking the tortillas!
