That sounds dangerous. An id() is only valid as long as the object it came from still exists, after which it can get re-used for a different object. So when an object is flushed from your cache, you would have to chase down all the places its id is being stored and eliminate them. Are you sure you couldn't achieve the same thing more safely using weak references? -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
