Actually that makes no difference, works just fine in 5.10. His problem is he expect Data::Dumper output to be identical. Maybe if he use $Data::Dumper::Sortkeys ... or this

#!/usr/bin/perl

use strict;
use warnings;

use Module::CoreList;
use Data::Dumper;

$Data::Dumper::Sortkeys=1;
print Dumper(
    $Module::CoreList::version{ $] },

    $Module::CoreList::version{ "$]" },
    $Module::CoreList::version{ 5.010000 }
);
__END__
$VAR1 = {
          'AnyDBM_File' => '1.00',
.....
        };
$VAR2 = $VAR1;
$VAR3 = $VAR1;
