**Bug report** The docstring of `enum.Enum` is invalid in reStructuredText since 3.11. ``` $ python3.11 ~/work/tmp/doc Python 3.11.0a7+ (heads/main:ad5e852, May 2 2022, 01:40:38) [Clang 11.0.3 (clang-1103.0.32.62)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import enum >>> print(enum.Enum.__doc__) (snip) - attribute access:: >>> Color.RED <Color.RED: 1> (snip) >>> ``` The "attribute access" line ends with a code-block marker "::". But no code-block follows. As a result, Sphinx emits a warning for the subclasses of Enum as following: ``` /Users/tkomiya/work/tmp/doc/example.py:docstring of example.Transpose:7: WARNING: Literal block expected; none found. ``` refs: https://github.com/sphinx-doc/sphinx/issues/10410 Additionally, the bullet list is interrupted by code-blocks. IMO, these code-blocks should be indented to the item level of the bullet list. **Your environment** - CPython versions tested on: Python 3.11.0a7+ (heads/main:ad5e852, May 2 2022, 01:40:38) - Operating system and architecture: macOS 10.15 <!-- gh-linked-prs --> ### Linked PRs * gh-92122 <!-- /gh-linked-prs -->
