in thread perspective and object-disorientation
This avoids monkeying with @ISA, which can only be a good thing. $attitude is an example of the Strategy Pattern. Note that I've not got an @args parameter to this function, instead I'd expect them to be wrapped up in teh $message object (which can be thought of as an example of the Argument Object pattern.sub respond_to_message_from { my $self = shift; my($message, $sender); my $attitude = $self->appropriate_attitude_to($sender); $attitude->respond_to_message_from($self, $message, $sender); }
