title: Multidimensional and associative array (hash) via POST in Perl/Catalyst
body: <p>In PHP, I would do this to get 'points' as an multidimensional array.</p>
  
  <pre><code>&lt;input type"text" name="points[0][1]" /&gt;
  &lt;input type"text" name="points[0][2]" /&gt;
  &lt;input type"text" name="points[1][1]" /&gt;
  &lt;input type"text" name="points[2][2]" /&gt;
  </code></pre>
  
  <p>Or if I wanted to get 'point' as an associative array:</p>
  
  <pre><code>&lt;input type"text" name="point[x_axis]" /&gt;
  &lt;input type"text" name="point[y_axis]" /&gt;
  </code></pre>
  
  <p>What is the Catalyst/Perl equivalent for such things?
  How can I get these through $c->req->params ??</p>
