title: Does die have to be used if opening a file fails?
body: <p>Most of time, I do something like this: </p>
  
  <pre><code>open FH, "&gt;file.txt" or die "Cann't open file: $!";
  </code></pre>
  
  <p>Does <code>die</code> have to be used? If I want my script to continue (and simply ignore the error if the file cannot be opened), what should I do?</p>
