New submission from STINNER Victor <vstin...@python.org>:
The PEP 563: Postponed evaluation of annotations was introduced an opt-in feature using "from __future__ import annotations". It is scheduled to become the default in Python 4.0. I would prefer to limit the number of incompatible changes in Python 4.0: it should just a "regular" release, with a regular number of incompatible changes. The version number change is going to cause enough troubles... Would it be possible possible to enable postponed evaluation of annotations either before or after Python 4.0? For example, can we imagine to enable it by default in Python 3.9? If not, what about Python 3.10? See also the PEP 608 (Coordinated Python release) and bpo-38604 (Schedule Py_UNICODE API removal). ---------- components: Library (Lib) messages: 355476 nosy: lukasz.langa, vstinner priority: normal severity: normal status: open title: [typing] PEP 563: Postponed evaluation of annotations: enable it by default before Python 4.0 versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38605> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
