There was a problem hiding this comment.
IIRC, we changed the Display impl to call into write_unraisable if the call to PyAny::str fails. Is this appropriate here? Should we call and_then(|obj| obj.as_ref(py).str().ok()) instead since we have an alternative fallback here?

Split off from #3306
This was a bug I noticed on pre-3.12 Pythons where the panic message would not be extracted correctly if the
PanicExceptionhad been normalised. After being fetched by PyO3 thePanicExceptionwould have its message reset to "Unwrapped panic from Python code".
