G'day rodinski,

Here's a possible solution. It doesn't require loading any modules. In the spirit of an idiom, I've greatly simplified the data: now you can see more idiom, less geography.

#!/usr/bin/env perl use strict; use warnings; my @posts = qw{a b c d}; my %fence = ( $posts[0], (map { $_ => $_ } @posts[1..$#posts-1]), $posts[-1] ); print "$_ to $fence{$_}\n" for @posts[0..$#posts-1]; my @extra = qw{w x y z}; my %info; $info{$posts[$_]}{extra} = $extra[$_] for 0..$#posts; print "$_~$info{$_}{extra}\n" for @posts;

Output:

a to b b to c c to d a~w b~x c~y d~z
