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

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

...quoting the contents of `Desktop/RunEveryCommand/Ruff/Broken/17333_parse90.py`, along with the `pyproject.toml` settings and executed command, we'd be very appreciative!

Is the initial example valid Python? I can't get that to parse under Python 3.11.

[charliermarsh]

❯ python foo.py
  File "/Users/crmarsh/workspace/ruff/foo.py", line 5
    line = *line.rstrip()
           ^^^^^^^^^^^^^^
SyntaxError: can't use starred expression here

I cannot find original file with this lines.

I tried to run this with several python versions and with each I had parse error, so the problem here is probably with recognizing this file by ruff as valid

[charliermarsh]

I think it's an error that Ruff doesn't flag the original source as invalid syntax.

Such files I reported upstream - RustPython/Parser#66

I'm going to close this one in favor of the RustPython issue.
