原来Ruby的module里的方法都能继承哦 Cool～

gistfile1.rb

class Something
  module Base  
    def my_method
      puts "(A) original functionality"
    end
  end

  module PreExtension
    def my_method
      puts "(B) before the original"
      super
    end
  end

  module PostExtension
    def my_method
      super
      puts "(C) after the original"
    end
  end

  include Base # this is needed to place the base methods in the inheritance stack
  include PreExtension # this will override the original my_method
  include PostExtension # this will override my_method defined in PreExtension
end

s = Something.new
s.my_method 
# => (B) before the original
# => (A) original functionality
# => (C) after the original
