Out of the mouths of dab'es ! Isn't this a 'sexeger' situation?

Maybe someone should check my results, 'cuz I can't believe that adding in the reverse's doesn't impact these timings more.   I added a different routine to the mix benchmarked by antirice:

sub badkcams {
  $a = reverse $s;
  $a =~ s[\cH[^\cH]|\cH$][]g  while  1+index $a, chr(8);
  reverse $a;
}

I then ran the benchmark again:

           Rate    smack     new1       uk badkcams
smack     191/s       --     -96%     -97%     -97%
new1     5063/s    2547%       --      -7%     -25%
uk       5469/s    2759%       8%       --     -19%
badkcams 6715/s    3411%      33%      23%       --
           Rate    smack     new1       uk badkcams
smack    42.4/s       --     -22%     -30%     -44%
new1     54.7/s      29%       --      -9%     -27%
uk       60.2/s      42%      10%       --     -20%
badkcams 75.3/s      78%      38%      25%       --

Am I reading this right?   It's faster?!?
