def foo(bar: list[str]) -> str | None:
    for baz in bar:
        match baz:
            case "yo":
                return sub_foo(baz)


def sub_foo(baz: str) -> str:
    return baz

failing command

(there's no pyproject.toml)

$ ruff check -n --fix --select RET503 .

error: Autofix introduced a syntax error. Reverting all changes.

This indicates a bug in `ruff`. If you could open an issue at:

    https://github.com/charliermarsh/ruff/issues/new?title=%5BAutofix%20error%5D

...quoting the contents of `foo.py`, along with the `pyproject.toml` settings and executed command, we'd be very appreciative!

foo.py:2:5: RET503 Missing explicit `return` at the end of function able to return non-`None` value
Found 1 error.
