title: Nesting included Twig templates?
body: <p>I'd like to pass the output of an included Twig template to another included Twig template as a parameter, like so:</p>
  
  <pre><code>{% include 'MyBundle:Default:tpl1.html.twig' with {'item': include 'MyBundle:Default:tpl2.html.twig'} %}
  </code></pre>
  
  <p>Unfortunately, this does not work as the syntax is invalid.
  Any ideas how to nest templates like this / store the output of an included template in a variable?
  Or is there an alternative way to accomplish what I want to do? I thought about defining blocks in the included template, but it does not seem to be possible to overwrite them from the "outer" template ...</p>
