Right. The major change is the changed settype() semantics, which can be one of two: class A { ... } $a = new A; settype($a, "B"); a) $a can now actually be a B, and have all slots and methods of B, or b) $a can now poseAs B, but still have the slots and methods of A. For some reasons I think that b) is the better was to handle this, but explaining that will lead to far for this evening (I would have to introduce some additional concepts such as delegates, which you will find not to be essential, but which are interesting in some more advanced designs).
