G'day polarbear,

What you are describing is the default behaviour for Data::Dumper. You can change it by setting $Data::Dumper::Deepcopy: 

$ perl -Mstrict -Mwarnings -e '
use Data::Dumper;
$Data::Dumper::Deepcopy = 1;

my @maintainers = qw/ worker@company.com manager@company.com /;

my %services = (
    service1 => { email => \@maintainers },
    service2 => { email => \@maintainers },
);

print Data::Dumper->Dump( [ \%services ], [qw/*services/] );
'
%services = (
              'service1' => {
                              'email' => [
                                           'worker@company.com',
                                           'manager@company.com'
                                         ]
                            },
              'service2' => {
                              'email' => [
                                           'worker@company.com',
                                           'manager@company.com'
                                         ]
                            }
            );

Update: I may have misinterpreted "I don't want the lists connected in any way." as the cross-referencing of the lists output by Data::Dumper rather than the lists pointed to by the arrayrefs. If this is the case, the email => [ @maintainers ] solution would be the way to go. Thanks, frozenwithjoy.
