Thanks. You and Robert have shown me the light. That paragraph was talking about the finalization that happens to a suspended generator when it is GC'd. Meanwhile, the contextmanager decorator ensures that its generator is run all the way through, so it would never be left in a suspended state, so its GC/finalization semantics are irrelevant. (Please correct, if wrong.) (Neil: I understood that it created a context manager object, but I had been reading the quoted paragraph to mean that by going through a generator the decorator was re-introducing a dependency on GC time. But I was wrong.) Regards, Johann -- http://mail.python.org/mailman/listinfo/python-list
