A simple test case repeats what I see in my code: 
#!/usr/local/bin/perl -w
#
# name: persistest
#
# does stuff
# works fine

use vars qw( %hash );
use strict;
use Persistence 'test.dat';


my ($k, $v, $n);
foreach (($k, $v) = each %hash) {
    $n++;
    print "$n: $k => $v\n";
}

%hash = ( blue => 'berries',
        red => 'roses',
        black => 'coffee',
        yellow => 'bananas',
        );

END { persistent '%hash'; }

produces 
$ ./persistest 
1:  => 
2:  =>

Warnings removed to improve readability. Why it iterates twice when it can't find the values, I can't figure.

perl -e 'print qq(Just another Perl Hacker\n)' # where's the irony switch?
