I just had another look at the documentation and it turns out there is a meta method that you can use to do what you want: 

for my $attr ( $meta->get_all_attributes ) {
      print $attr->name, "\n";
  }

[download]
(from the MOP documentation). Prints out all attributes including inherited ones. To use it, I guess you should only define a BUILD method in the Parent class, where you replace your loop through the attributes by the above.
