The following is quite ugly and either the keys or the values need to be typed in twice, but I just couldn't get closer to the solution (if there is one): 
#!perl

use strict;
use warnings;

foreach my $val ( qw/ one one three two one / ) {
    print scalar { 
             map { @{[(qw/one two three/, reverse (1..3))]}[$_ - 1, -$
+_] } 
                (1..(2 * @{[1..3]}))
          }->{$val},
          "\n";
}

or just typed in once, but with one additional variable used within the outer map 
#!perl

use strict;
use warnings;

foreach my $val ( qw/ one one three two one / ) {
    print scalar { 
                map {
                       my $intern = $_;
                       map { @{$intern}[$_ - 1, -$_] }
                           (1..@{$_})
                    }
                    ([(qw/one two three/, reverse (1..3))])
          }->{$val},
          "\n";
}

I could of course (ab)use an internal variable, but it remains another variable. Anyone have an idea?
