I've written a fair bit of library code, and I've never found a pressing need to test for an abstract interface. In the rare cases where I've used type testing in an API, it's always been for specific well-known concrete types, such as strings and tuples -- never anything so abstract as "iterator", "sequence", etc. -- Greg _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
