Well, we tend to avoid single boolean arguments in favor of differently named functions. But here is an alternate API: expose the state by having a 'cache_stat' attribute of the Path that is 'False' by default but can be set 'True'. It could also (or only?) be set via an optional constructor argument. --David _______________________________________________ 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
