Here's a slightly cleaner version, showing that you can fully wrap the
class method.

module Foo
  def initialize( *args )
    self.extend Foo::Stuff
  end
  module Stuff
    def bar
      puts "before class"
      super
      puts "after class"
    end
  end
end

class Bar
  include Foo
  def initialize
    super
  end
  def bar
    puts "in class"
  end
end

goof = Bar.new
goof.bar
#=> before class
#=> in class
#=> after class
