That's not a strong feature, but still, it makes the tool a little bit more comfortable to use. Oh, and an other benefit of the handle is that it gives a rough estimation of the number of objects created and their instantiation order. When debugging, any hints count. For VarDumper, I don't need spl_objet_id(). As we spotted, the code is already able to get the number it needs. Having spl_object_id() is still a feature that is not exposed to userland, but that is useful as I tried to demonstrate.
