New submission from Antony Lee <anntzer....@gmail.com>:
https://bugs.python.org/issue36350 / https://github.com/python/cpython/pull/12412 changed Signature.parameters and BoundArguments.arguments to be plain dicts, not OrderedDicts (for Py3.9a4). Even though I agree for BoundArguments.arguments (in fact I argued for this behavior in https://bugs.python.org/issue23080), I think Signature.parameters should remain OrderedDicts. Otherwise, one would get >>> inspect.signature(lambda x, y: None).parameters == inspect.signature(lambda y, x: None).parameters True which seems plain wrong (comparing the signature objects themselves still correctly return False because __eq__ explicitly considers parameter order, but one may e.g. want to compare parameters for equality while ignoring the return annotation). ---------- components: Library (Lib) messages: 362800 nosy: Antony.Lee priority: normal severity: normal status: open title: inspect.Signature.parameters should be an OrderedDict, not a plain dict versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39775> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
