New submission from Gregory P. Smith <g...@krypto.org>:
Based on the PEP 617 acceptance thread on python-dev, lib2to3 is eventually going to run into trouble parsing modern syntax a few releases from now. It would be better off maintained outside of the standard library. It gets used by a lot of things and is generally useful, but would make a lot more sense as a PyPI project than as something only quasi-maintained within the stdlib (it only gained the ability to parse a couple modern syntax features in via bugfix contributions to the stdlib the past month or two... meaning a lot of versions of it out there cannot) Black has already forked it. goal: PendingDeprecationWarning and documentation as such in 3.9. Move to DeprecationWarning in 3.10 or 3.11 and remove it by ~3.12. Subject to our existing deprecation process guidelines. ---------- assignee: gregory.p.smith messages: 366973 nosy: gregory.p.smith priority: normal severity: normal status: open title: Deprecate lib2to3 (and 2to3) for future removal type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40360> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
