title: How can I sum arrays element-wise in Perl?
body: <p>I have two arrays:</p>
  
  <pre><code>@arr1 = ( 1, 0, 0, 0, 1 );
  @arr2 = ( 1, 1, 0, 1, 1 );
  </code></pre>
  
  <p>I want to sum items of both arrays to get new one like</p>
  
  <pre><code>( 2, 1, 0, 1, 2 );
  </code></pre>
  
  <p>Can I do it without looping through arrays?</p>
