title: Symfony 2 service with multiple instances?
body: <p>I read this: <a href="http://symfony.com/doc/current/book/service_container.html">http://symfony.com/doc/current/book/service_container.html</a></p>
  
  <p>It said:</p>
  
  <pre><code>$mailer = $this-&gt;get('my_mailer');
  </code></pre>
  
  <blockquote>
    <p>As an added bonus, the Mailer service is only created once and the
    same instance is returned each time you ask for the service. This is
    almost always the behavior you'll need (it's more flexible and
    powerful), <strong>but we'll learn later how you can configure a service that
    has multiple instances.</strong></p>
  </blockquote>
  
  <p>How do I make my service to have multiple instances -- i.e. whenever I reach the service I am given a new instance? Something like <code>$this-&gt;getNew()</code> or something?</p>
