Muhuhahaha! Scott is trying to escape! Little does he know that you can
never unsubscribe from the evil
boulder Perl-Mongers list (Well, at least not without sending E-mail to
majordomo *grin*)

(Let's fill up his inbox with useless perl stuff! quick everyone! I'll
start...

Hey, This is an oddity:

Of these two code fragments:

   @{$me->{arrayrep}} = split(/(?=$me->{break})/,$value); 
   my $mypos = 0;
   foreach $line (@{$me->{arrayrep}})
   {
     $mypos += length($line);
     ... do stuff ...
   }

and

    while ($value =~ /$me->{break}/g)
    {
      my $mypos = pos($value);
      $me->{arrayrep}->[$i] = $1;
      $i++;
      ... do stuff ...
    }

I would think that the first (Which calls the 'split' builtin to generate
the array)
would be faster than the second (Which repeatedly does a regular expression
and assigns the list elements by hand)

But in fact it's the reverse! Weird eh?
Anyone have a good explination for why?
