That was just a VERY basic example of creating $client and yes I do use strict,
warning and checking for connection errors ;)

There is _NOTHING_ in it (I'm thinking an undefined value), when I try to match
against the variable supposedly containing the incoming data and supposedly
actually contain something. The result is the too familiar 'uninitialized
value' warning. Even doing thus:
while (defined(my $data = <$client>)) {
Still results in the same oddity. and even checking the variable underneath
with defined() still does not work.
