OK, I think I understand a little better what you were trying to accomplish.

This seems to correctly return all the files in the File::System in a hash of hashes:

#!/usr/bin/perl

use strict;
use Data::Dumper;
use File::Find;
use File::System;

my $root = File::System->new( "Real", root => '/etc' );

my %files = map {
    my $file = $_;
    my %attrs = map { $_ => $file->get_property($_); } ( $_->propertie
+s() );
    $file => \%attrs;
} $root->find( sub { 1 }, () );

print Dumper \%files;

I realise that doesn't completely do what you want, but it seems to at least get the complete file tree back, without empty hashes...

To be perfectly honest, I generally use File::Find out of a sense of guilt: I really prefer the interface from File::System::Object $obj -> find()
