Since we're being facetious, here's my replacement for loops. (If Perl could evaluate $data[$i][0..$#{$data[$i]}][$j] I wouldn't need the for loops at all.) 
#!/your/perl/here

use strict;
use warnings;

# backwhack whitespace
my @data = 
(
    [
        [1, 'Darth\ Vader'],
        [3, 'Luke\ Skywalker'],
        [5, 'Obi\ Wan\ Kenobi'],
    ],[
        # note stray trailing blank here
        [0, 'Lighsabre\ '], 
        [5, 'Blaster'],
        [9, 'Rocket\ launcher'],
    ],[
        [10, 'Dagobah'],
        [14, 'Kashyyyk'],
    ],
);

# transpose innermost 2D matrices
my @new_data;
foreach my $set ( 0..$#data )
{
    foreach my $pairs ( 0..$#{$data[$set]} )
    {
        foreach my $items ( 0..$#{$data[$set][$pairs]} )
        {
            $new_data[$set][$items][$pairs] = $data[$set][$pairs][$ite
+ms];
        }
    }
}

# comma-separated pattern specs for glob
$"=',';

# had to break this in two because of tab and newline issues
my $glob1 = "{@{$new_data[0][0]}}{@{$new_data[1][0]}}{@{$new_data[2][0
+]}}";
my $glob2 = "{@{$new_data[0][1]}}" . '\,\ ' . "{@{$new_data[1][1]}}" .
+ '\,\ ' . "{@{$new_data[2][1]}}";

my @glob1 = glob $glob1;
my @glob2 = glob $glob2;

print map {"$glob1[$_]\t$glob2[$_]\n"} 0..$#glob1;
