New submission from Mark Dickinson: Passing a weakref.ref callback by keyword currently fails silently:
Python 3.4.0a0 (default:537c1f1ab53c, Apr 16 2013, 20:07:47) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import weakref >>> weakref.ref({1, 2, 3}, callback=lambda ref:print("collected")) <weakref at 0x1006189d8; dead> For Python 3.4, I'd suggest that either (1) this should be an exception, or (2) it should be permissible to pass the callback by keyword. ---------- messages: 187115 nosy: mark.dickinson priority: normal severity: normal stage: needs patch status: open title: weakref.ref ignores a 'callback' keyword argument type: enhancement versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17765> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
