the following will not work:

the following works fine:

foreach my $a (0..$what){
        foreach my $b (0..$why){
                $arrayref_one->[$a]->[$b] = $arrayref_two->[$a]->[$b];
        }
}
it would be nice to have something to copy complex data structures that
isn't going to be a code maintenance headache-  the above is dependent
on the data structure being a "2 dimensional array" of particular size.
i don't want that restriction.
any help would be apreciated :)
From the Perl Cookbook (2nd Edition), recipe 11.12:

use Storable;
$arrayref_one = dclone( $arrayref_two );
