This seems to work

BEGIN{
    use Data::Dump::Streamer();
    package Data::Dump::Streamer;
    use overload '""' => sub { return $_[0]->Out };
}

use Data::Dump::Streamer;

print Dump({1,2}),"\n\n";
print Dump({1,2})."\n\n";
__END__

adding use overload '""' => sub { return $_[0]->Out }; to Data-Dump-Streamer-2.09/lib/Data/Dump/Streamer.pm breaks these tests
