This node is here to demonstrate how upgrading your Perl can automagically make your life easier. The following code does not work as expected in 5.8.0, but does so in 5.8.6

sub sequential {
  my $self    = shift;
  my $sl_ctl  = $self->{slctl};
  my $sl_len  = scalar(@$sl_ctl);
  my $mode    = $self->{params}->{mode};
  my $m_clust = $mt_param{$mode}->{cluster};
  my @tl_rtl  = ();

  &log("mt: entering sequential, mode >$mode<...\n");

  $m_clust = &get_maxval([1, $m_clust]);

  for(my $i = 0; $i < $sl_len; $i++) {
    my $idx_la = &get_minval([$sl_len-1,
                     $i + $m_clust]);
    my $phrase;
    my $rawtr;
  retry:

    &log("I: $i IDX_LA: $idx_la\n");

    $phrase = join ' ', @$sl_ctl[$i..$idx_la];
    $rawtr  = $self->get_rawtr($phrase);
    if(@$rawtr) {
      my $disam = $self->disambiguate($phrase,
                        $rawtr,
                        $i,$idx_la);
      push @tl_rtl, $disam;
    } else {
      if($idx_la > $i) {
      $idx_la--;
      goto retry;
      }
      push @tl_rtl, $phrase;
    }
    $i = $idx_la;
  }

  @tl_rtl = &trim(@tl_rtl);
  $self->{tlrtl} = \@tl_rtl;

  return TRUE;
}

In correct operation, the log looks like this, You see, $idx_la is always defined
