In the context of this discussion it is. We are talking about about automatic cleanup and whether it should happen immediatly after a name is no longer available. or wait until the object is garbage collected. The fact that I used a del for illustrating the possible problems is just a detail. That other languages may have different semantics with the del statement is irrelevant. -- Antoon Pardon -- https://mail.python.org/mailman/listinfo/python-list
