title: Perl how to check if array is still empty?
body: <p>This should be simple hopefully. I initialize an empty array, do a grep and place the results (if any) in it, and then check if it's empty. Like so:</p>
  
  <pre><code>my @match = ();
  @match = grep /$pattern/, @someOtherArray;
  if (#match is empty#) {
      #do something!
  }
  </code></pre>
  
  <p>What's the standard way of doing this? </p>
