title: does twig has any limitations
body: <p>Does twig have any kinda limitations?
  since i have huge array and I am trying to render it with twig. And it just dies, I mean it does not generates template at all. i see just blank page, no error, nothing. I am using symfony2. I tried to change template engine to php and it's worked. So i am just interested is there are some kinda limitations. And why it does not gives me an error.. </p>
  
  <p>twig code:</p>
  
  <pre><code>{% extends '::base.html.twig' %}
  
  {% block body %}
  
  &lt;h3&gt;test&lt;/h3&gt;
  
  {% for group in results.groups %}
      {% for link in group.links %}
          &lt;a href="{{link.link}}"&gt;{{link.link}}&lt;/a&gt;
          &lt;br&gt;
          {% for key,keyword in link.keywords %}
              &lt;span&gt;{{keyword}} =&gt;{{key}};&lt;/span&gt;
          {% endfor %}
      {% endfor %}
      {% for keyword in keywords %}
          &lt;p&gt;{{keyword}}&lt;/p&gt;
      {% endfor %}
  {% endfor %}
  {% endblock %}
  </code></pre>
  
  <p>it's just to show results for client so i don't need speed or something. (I have like about 1k groups every group has about 50 links every link has 100 keywords ). If I remove the loop test becomes visible in template else I have blank page.</p>
