Of course you can!

But if you only want to show the content of the hash (not use or manipulate them) then Data::Dumper and its brethren will come in very handy.

use Modern::Perl qw /2014/;
use Data::Dumper ;

my %Hash;
$Hash{a}[0]="i";
$Hash{a}[1]="ii";
$Hash{a}[2]="iii";
$Hash{b}[0]="iv";
$Hash{b}[1]="v";
$Hash{b}[2]="vi";

say Dumper (\%Hash);

Output:

$VAR1 = {
          'b' => [
                   'iv',
                   'v',
                   'vi'
                 ],
          'a' => [
                   'i',
                   'ii',
                   'iii'
                 ]
        };
