Isn't the "with" statement appropriate in these cases? My assumption is/was that the benefit of warning against leaks in real applications (or even - sigh - the standard library) would outweigh the inconvenience when hacking together a quick script. But if it doesn't, what about enabling it with a command-line switch? _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
