"self" in a class is annoying and errorprone

Not to confuse the issue, but in methods, perl *does* require a self;
the object itself is the first argument in any method call, and
referencing into it is the way you get at members; there are, of
course, far too many ways to do this, but something like
sub consider {
my $self = shift;
my $port = $self->{nextport};
$self->{nextport}++;
...
}
is one of the more common and readable forms (in particular, it's the
form you'll find in examples and documentation.) You could call it
something else, or even use $_[0] directly, but that's the only way
you're going to actually find the object members...
