"Note that a socket which fails to connect does not return a false value."

This is definitely wrong, otherwise why the following worked for me:

use IO::Socket::INET;

use strict;
use warnings;

IO::Socket::INET->new(Proto => "tcp", PeerAddr => "123.123.123.123", P
+eerPort => 123, Timeout => 10) || die "failed to connect";

If whatever before 'or' was not evaluated to false, why should the die get evaluated, and print the message on screen for me?
