Ok, I spent a lot more time on this. I got it back to a one step process while using your idea to create iterator objects AND can do multiple iterators now. Woot! 

sub AUTOLOAD {
  our $AUTOLOAD;
  my $s = shift;
  $AUTOLOAD  =~ /.*::get(_next)*(_\w+)_files*$/ or
    croak "No such method: $AUTOLOAD";
  my ($next, $type) = ($1, $2);

  # Handle edge case when get_next_file() method is called
  if (!$next && $type eq '_next') {
    $next = 1;
    $type = '';
  }

  # return the requested list of files
  if (!$next) {
    my $attr = "${type}_files";
    my @files = @{$s->{$attr}};
    return @files;
  }

  # get a single file from an iterator
  if ($s->{"_iterator_$type"}) {
    my $file = $s->{"_iterator_$type"}->next_file;
    $s->{_last_iterator_file} = $file;
    undef $s->{"_iterator_$type"} if (!$file);
    return $file;
  } else {
    my @files = $type ? @{$s->{"${type}_files"}} : $s->get_files;
    return '' if !@files;
    my $class = ref($s) . '::Iterator';
    $s->{"_iterator_$type"} = $class->new(@files);
    $s->{_last_iterator_file} = $s->{"_iterator_$type"}->selected_file
+;
    return $s->{"_iterator_$type"}->selected_file;
  }
}

sub selected_file {
  my $s = shift;
  return $s->{_last_iterator_file};
}

Now I can do nested loops: 

  while ($fp->get_next_file) {
    print $fp->selected_file . "\n";
    while ($fp->get_next_nonparseable_file) {
      print $fp->selected_file . "\n";
    }
  }

Thanks so much for the pointers and getting me to think hard about this. Much appreciated!
