I should have read the question better before I answered :-)
The code I gave will only dereference down 1 layer.
The code below will explain this better, I hope.
Anyway, I think what you really want is Clone.
I just downloaded it to test this code, and already I see it as an invaluable tool in my Perl toolbox.
Here is an example of how my earlier code fails, and how Clone can help you.

Good luck

#!/usr/bin/perl -w

use strict;
use Clone qw(clone);

my $original =[1,2,[3,4,5]];

my $shallow_original=$original;
my $deep_original=[@$original]; #deep, but not deep enough!!
my $clone_original=clone($original); # this behaves fine.

$original->[1]=42;
$original->[2][1]=77;

print "original: @$original\n";
print "shallow: @$shallow_original\n";
print "deep: @$deep_original\n";

print "shallow[2][1]: $shallow_original->[2][1]\n";
print "deep[2][1]: $deep_original->[2][1]\n";
print "clone[2][1]: $clone_original->[2][1]\n";

The output of which is

original: 1 42 ARRAY(0x80cf9a4)
shallow: 1 42 ARRAY(0x80cf9a4)
deep: 1 2 ARRAY(0x80cf9a4)
shallow[2][1]: 77
deep[2][1]: 77
clone[2][1]: 4
