title: check if variable is of type array in fluid
body: <p>Is it possible in fluid to check if the type of a variable is an array? I search for something like this.</p>
  
  <pre><code>&lt;f:if condition='{myvar.Type == "Array"}'&gt;&lt;/f:if&gt;
  </code></pre>
  
  <p>Or do I have to create my own ViewHelper for this purpose?</p>
