On the other hand in many situations it is useful to be able to pass an empty value, e.g. setHandler(HandlerClass $a) could be called with setHandler(null) to remove the handler. For string values you can pass an empty string, for numbers 0 or a negative number and for objects null. In other languages it is always possible to pass null instead of the object (e.g. Java), in C/C++, every pointer may be set to null. I agree that it is a bad idea to introduce another weird syntax. We should either always allow null or never. I would prefer the first solution but could easily live with the second. -- Ferdinand Beyer <fb@fbeyer.com>
