I've started adding a brief "self help" snippet in code that I write for others. This allows them to enter command -help from the command line and get the POD doc. We're still on Perl 5.005 here, so I'd guess that the warnings either don't appear in 5.6, or at least can be ignored with no warnings.
#!/usr/local/bin/perl -w

use strict;
use Getopt::Long;
use Pod::Text;


(my $PROGRAM = (split('/',$0))[-1]) =~ s/\..*$//;
my $USAGE = <<__EOT__;
Usage: $PROGRAM [-help]
__EOT__


my $HELP;

# Get the command-line parameters
GetOptions("help" => \$HELP)
  or die($USAGE);

if ($HELP)
{
  $^W = 0;  # Pod::Text throws warnings
  pod2text($0);
  exit(0);
}

# Continue with the rest of the program
