All of my perl knowledge is self-taught through O'Reilly books and the Internet. Oftentimes I've been told that my code is ugly, or not well-formed, while it looks perfectly functional to me. Is there a reference somewhere, or a book I should read that would help me write better or cleaner code. I really don't want to write any more fodder for http://thedailywtf.com Edit: Someone asked for a sample, so here's a widget for my current project: 
#!c:\perl\bin\perl.exe -w
use strict;
use Crypt::Twofish_PP;

my $crypt = Crypt::Twofish_PP->new("innatelyinsecure");

if (!($ARGV[0])) {
  die "Syntax: crypt.pl (-e|-d) Text";
} elsif ($ARGV[2]) {
  die "incorrect syntax";
} elsif (!($ARGV[0] =~ /^-/)) {
  die "first argument must be mode. (-e or -d)";
} else {
  if ($ARGV[0] =~ /^-e$/) {
    my $result = $crypt->encrypt($ARGV[1]);
    print $result;
  }elsif ($ARGV[0] =~ /^-d$/) {
    my $result = $crypt->decrypt($ARGV[1]);
    print $result;
  }else{
    print "Invalid mode argument (must be -e or -d)";
  }
}
