Hi! > There the assumption would be that this leads to an array $a with two > elements, where in fact there is only one if __toString() is being > called. The only thing "making sense" would be using using the objects > identity (i.e. via spl_object_hash()) everything else leads to issues. This is a valid concern. For this, Java, for example, has separate methods hashCode() and toString(). Python has __str__, __repr__ and __hash__. Ruby has object.hash. So maybe we should have another magic, something like __hash(), that would produce a value for key? Then objects that implement __hash would be hashable and those that don't won't be, while still having usable __toString. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/
