title: what does STDOUT->autoflush(1) do in Perl?
body: <p>I've found a variety of information regarding autoflushing in Perl, but can't find any mention of a line formatted exactly like this:</p>
  
  <pre><code>STDOUT-&gt;autoflush(1);
  </code></pre>
  
  <p>This is included in a program I'm analyzing, and I want to understand better what it does. There is also this at the beginning of the program:</p>
  
  <pre><code>use IO::Handle;
  </code></pre>
  
  <p>...which I think might be related, but it also doesn't mention this method in its documentation. </p>
