Hi cammac,

Why not just try it? ... 

use strict;
use warnings;

use Data::Dumper;

my $parray = [ qw( a b c ) ];

printf "Array before change is:  %s\n", Dumper($parray);

my $phash = {
    'array' => $parray,
};

printf "Hash before change is:  %s\n", Dumper($phash);

push @$parray, 'd', 'e', 'f';

printf "Array after change is:  %s\n", Dumper($parray);
printf "Hash after change is:  %s\n", Dumper($phash);

The results indicate that you do NOT need to do anything manually: 

Array before change is:  $VAR1 = [
          'a',
          'b',
          'c'
        ];
 
Hash before change is:  $VAR1 = {
          'array' => [
                       'a',
                       'b',
                       'c'
                     ]
        };
