I'm writing a module using DB_File. The data seems to get saved to the file 'test.db' but fetching or Data::Dumper() the file doesn't seem to dump the data. Here's what I have so far: 

package SubscriberList;

use strict;
use warnings;
use vars qw($VERSION);

$VERSION     = '0.01';

use Data::Dumper;
use DB_File;
use Storable qw(freeze thaw);

sub new
{
  my ($class,%args) = @_;

  # get args
  my $this;
  $this->{filename} = $args{filename};
  tie %{$this->{db}}, 'DB_File', $this->{filename};

  bless $this, $class;
  return $this;
}

sub DESTROY
  {
    my ($this) = @_;
    untie %{$this->{db}};
  }

sub add_subscriber
  {
    my ($this,%new_sub) = @_;
    
    my $email = $new_sub{email};
    delete $new_sub{email};

    $this->{db}->{$email} = freeze \%new_sub;

    return $this;
  }
1;

...and here is the test script to add an entry: 
# test.pl
use SubscriberList;

$list = new SubscriberList(filename=>'test.db');

$list->add_subscriber(
                email=>'new@email.com',
              first_name => 'New',
              last_name  => 'Subscriber',
               );

$list->add_subscriber(
                email=>'jar@jar.com',
              first_name => 'JarJar',
              last_name  => 'Binks',
               );

...and here is the code that dumps the seemingly empty data file: 
use Data::Dumper;
use DB_File;
tie %hash, 'DB_File', 'test.db';
print Dumper(\%hash);

############
Ouput
$VAR1 = {};

The 'test.db' file seems to have data in it because when I run it through the command 'strings' all the values seem to be there.

Any suggestions? (besides go to bed and try agian tomorrow? ;-)

Cheers!
