while I was looking at the source of POE::Driver::SysRW, I saw the line: {% use_bytes %}, what is the syntax? what does it mean? Thanks. The full method is as follows: 
sub put {
  my ($self, $chunks) = @_;
  my $old_queue_octets = $self->[TOTAL_OCTETS_LEFT];

  {% use_bytes %}

  foreach (grep { length } @$chunks) {
    $self->[TOTAL_OCTETS_LEFT] += length;
    push @{$self->[OUTPUT_QUEUE]}, $_;
  }

  if ($self->[TOTAL_OCTETS_LEFT] && (!$old_queue_octets)) {
    $self->[CURRENT_OCTETS_LEFT] = length($self->[OUTPUT_QUEUE]->[0]);
    $self->[CURRENT_OCTETS_DONE] = 0;
  }

  $self->[TOTAL_OCTETS_LEFT];
}
