title: How can I loop through a Perl array of arrays of hashes?
body: <p>I would like to print an Array of Arrays of Hashes, so I looked at <a href="http://perldoc.perl.org/perldsc.html#ARRAYS-OF-ARRAYS" rel="nofollow noreferrer">perldsc</a>, and ended up with</p>
  
  <pre><code>for my $j (0 .. $#aoaoh) {
      for my $aref (@aoaoh) {
      print '"' . join('","', @$aref[$j]), "\"\n";
      }
  }
  </code></pre>
