| In ``importlib.metadata``, restore compatibility in the result from |
| ``Distribution.entry_points`` (``EntryPoints``) to honor expectations in |
| older implementations and issuing deprecation warnings for these cases: A. |
| ``EntryPoints`` objects are once again mutable, allowing for ``sort()`` |
| and other list-based mutation operations. Avoid deprecation warnings by |
| casting to a mutable sequence (e.g. ``list(dist.entry_points).sort()``). |
| B. ``EntryPoints`` results once again allow for access by index. To avoid |
| deprecation warnings, cast the result to a Sequence first (e.g. |
| ``tuple(dist.entry_points)[0]``). |
