I'm having some lovehate with File::Find::Rule.. Why doesn't this find empty dirs??

use File::Find::Rule;
use Smart::Comments '###';

my $path = '/home/myself';

mkdir "$path/nothing";

my $finder= File::Find::Rule->new;
$finder->directory();
$finder->empty();
my @found = $finder->in($path);
### @found
[download]

Is it because it's just testing for file (as in file, not dir) size?

update This seems to work :

use IO::Dir;
use File::Find::Rule;

sub _is_empty_dir {
  my ($shortname, $path, $fullname) = @_;
  my $dh = IO::Dir->new($fullname) or return;
  my $count = scalar(grep{!/^\.\.?$/} $dh->read());
  $dh->close();
  return($count==0);
}

sub emptydirfinder {
    my ($self,$abs) = shift; $abs or die();
    
    my $finder= File::Find::Rule->new;
    $finder->directory();
    $finder->exec( \&_is_empty_dir);

    my @found = $finder->in($abs);
    return \@found;
}
