I don't like the idea of editing the code each time. So, I offer the following slightly different version: 
package GOLF;

use strict;

my $code = join '', <>;

$code =~ s/^\s+|\s+$//gm;
$code =~ s/\n//g;
$code =~ s/}$//;
$code =~ s/^sub\s+(\w+)\s*{//;

printf "Length of sub '$1' => %d chars\n", length $code;

This way you can put GolfScore.pl (what I called it) into your path, work on your golf games in a temp directory and know for sure that you're scoring what you're running.

Have fun,
