I'm not getting the same results as everyone else: 

#!/usr/bin/perl -w

use strict;
use Benchmark;

my $string = " field1 , field2 , field3 , field4 , 
     field5 , field6 , field7 , field8 , field9 , 
     field10 , field11 , field12 "; 

sub regexp {
    $string =~ m#^(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*),(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*),(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*),(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*),(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*),(\s*)(\w*?)(\s*),
     (\s*)(\w*?)(\s*)$#o;
    my $s = $11;
    print $s;
}

sub splitter {
    my $s = (split(/\s*,\s*/, $string))[3];
    print $s;
}

Is there something wrong with my code? I know that isn't the best regular expression ever created, but I would like to know why it doesn't beat the split.

Note: To whomever I saw with the shell prompt like I have above, that is so cool!
