title: Does an equivalent to prepend method exist in ruby 1.9.3?
body: <p>I need to use the <a href="http://ruby-doc.org/core-2.0/Module.html#method-i-prepend" rel="nofollow"><code>prepend</code></a> method, introduced in ruby 2.0, in ruby 1.9.3, where this method is not supported. Is there an equivalent method in ruby 1.9.3?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I need this working with ruby 1.9.3</p>
  
  <pre><code>module ActiveAdmin::Views::Pages::BaseExtension
    def add_classes_to_body
      super
      @body.set_attribute "ng-app", "MyApp" #I need to add this line
    end
  end
  class ActiveAdmin::Views::Pages::Base
    prepend ActiveAdmin::Views::Pages::BaseExtension
  end
  </code></pre>
