title: Ant flaka: modify each elements of a list
body: <p>I have this list:</p>
  
  <pre><code>&lt;c:let&gt;
      a = list('a','b','c')
  &lt;/c:let&gt;
  </code></pre>
  
  <p>How can i modify each elements for that list?</p>
  
  <p>I need something like:</p>
  
  <pre><code>for (int i = 0; i &lt; a.length; i++) {
      a[i] += 'd';
  }
  </code></pre>
  
  <p>I looked in the tutorial, but the examples show only how to retrieve a list element, not how to modify it.</p>
  
  <p>So, <strong>how can i modify list elements, iterating on it?</strong></p>
  
  <p><em>Thanks!</em></p>
