title: Extending of Symfony container
body: <p>is it possible overwrite/extend <code>Symfony\Component\DependencyInjection\Container::get()</code> method? I want automatic creating service, when it is not contain in container, but class of service exists. </p>
  
  <p>For example:
  Name of service is <code>My.MyBundle.Model.FooRepository</code>
  Service with this name doesnt exists, but when i call:</p>
  
  <pre><code>$container-&gt;get('My.MyBundle.Model.FooRepository');
  </code></pre>
  
  <p>check class_exists for <code>\My\MyBundle\Model\FooRepository</code> and when its exists, add to container and return it. Dependencies of this new services will be resolve by <code>kutny/autowiring-bundle</code>.</p>
  
  <p>This feature can be extended only for some namespaces or interfaces and in production enviroment can be cached, but for developing will be great helper.</p>
  
  <p>Any idea?</p>
