Sure, but you can refer directly to objects, pass objects around, and refer to individual objects. This is abstract in the sense that it is far removed from the memory representation. However, the concept of a reference appears only when you explain how objects are handled (semantics). You cannot reference nor manipulate a reference in python, and that IMHO makes them more abstract. -- :-- Hans Georg -- http://mail.python.org/mailman/listinfo/python-list
