title: Perl Switch Statement
body: <p>Is there any way to run a block of code if none of the case blocks were matched? For instance:</p>
  
  <pre><code>switch($a) {
  
    case // {}
    case // {}
    ...
    # DO SOMETHING IF NONE OF THE ABOVE CASES WERE MATCHED
  }
  </code></pre>
  
  <p><code>else</code> is not what I'm looking for, since it applies only to the last case block.</p>
