行列転置

これより短い方法はあるのだろうか？

$ perl -MData::Dumper -MList::Util -e '
$foo = +[+[11,12],+[21,22,23],+[31],+[41,42]];
print Dumper($foo);
$bar=+[];
for $i (0..List::Util::max(map{$#$_}@$foo)){
  push @$bar , +[ map {$_->[$i]} @$foo ]
};
print Dumper($bar);
'
$VAR1 = [
          [
            11,
            12
          ],
          [
            21,
            22,
            23
          ],
          [
            31
          ],
          [
            41,
            42

            41
          ],
