-PEP 563: Postponed Evaluation of Annotations Becomes Default
-------------------------------------------------------------
-
-In Python 3.7, postponed evaluation of annotations was added,
-to be enabled with a ``from __future__ import annotations``
-directive.  In 3.10 this became the default behavior, even
-without that future directive.  With this being default, all
-annotations stored in :attr:`__annotations__` will be strings.
-If needed, annotations can be resolved at runtime using
-:func:`typing.get_type_hints`.  See :pep:`563` for a full
-description.  Also, the :func:`inspect.signature` will try to
-resolve types from now on, and when it fails it will fall back to
-showing the string annotations.  (Contributed by Batuhan Taskaya
-in :issue:`38605`.)
