title: Rails Interactor rollbacks
body: <p>I am using the <a href="https://github.com/collectiveidea/interactor" rel="nofollow">interactor gem</a> in my rails project. When one of the interactors within the organizer fails, the rollback method is called. The question is, is there any way this method can be aware of why the interactor failed?</p>
  
  <p>Example:</p>
  
  <pre><code>def call
    context.fail! error: 'Some error'
  end
  
  def rollback
    # I want to access 'Some error' here
  end
  </code></pre>
