``from __future__ import annotations`` was previously scheduled to
become mandatory in Python 3.10, but the Python Steering Council
twice decided to delay the change
(`announcement for Python 3.10 <https://mail.python.org/archives/list/python-dev@python.org/message/CLVXXPQ2T2LQ5MP2Y53VVQFCXYWQJHKZ/>`__;
`announcement for Python 3.11 <https://mail.python.org/archives/list/python-dev@python.org/message/VIZEBX5EYMSYIJNDBF6DMUMZOCWHARSO/>`__).
No final decision has been made yet. See also :pep:`563` and :pep:`649`.
