Well I program my BINDs and ASSIGNs such way that they check if the value has changed or not. It is part of my 'defensive programming' strategy. Esspecially within those kind of procedures you'll have to be very carefull, because the developper accessing the property might not have a clue that it is calling some additional code. Therefore I'd like to avoid BIND and ASSIGN procedures unless there is no other convenient way out or something has to be totally transparent and hidden deep in a class without any outside dependencies.
