Nick Coghlan added the comment: We can't make ordinary generators innately context managers, as it makes the error too hard to detect when you accidentally leave out @contextmanager when using a generator to write a custom one.
You can already use contextlib.closing to forcibly close them when appropriate, so providing a decorator to implicitly map __exit__ to close wouldn't really save much. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17468> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
