Subject: Re: How does Module#include differ from #prepend?

@Hans sorry for that. Actually I ran the code all at a time,thus result 
misleads to me. Now it is set.

class Foo
  def do_stuff
    puts "doing stuff"
  end
end

module Wrapper
  def do_stuff
    puts "before stuff"
    super
    puts "after stuff"
  end
end

class Foo
  prepend Wrapper
end

p Foo.ancestors #=> [Wrapper, Foo, Object, Kernel, BasicObject]

class Foo
  def do_stuff
    puts "doing stuff"
  end
end

module Wrapper
  def do_stuff
    puts "before stuff"
    super
    puts "after stuff"
  end
end

class Foo
  include Wrapper
end

p Foo.ancestors #=> [Foo, Wrapper, Object, Kernel, BasicObject]
