If you nab mapcar[0] this is insanely simple
use mapcar;
use Data::Dumper;
my $arrays= [ [1..3], [5..7] ];
my @reordered = mapcar { [EMAIL PROTECTED] } @$arrays;
print Dumper([EMAIL PROTECTED]);

Shortly to be released to CPAN as Maptastic, as soon as I figure out

Pre-release available at http://vilain.net/pm/Maptastic-0.99.tar.gz,

How do I do that? I mean, I can write this code:

foreach my $col_no (0..(@{ $_[0]-[0] } - 1))
{
