Summary
repr()implementations ofstaticmethodandclassmethod.staticmethodandclassmethodusedrepr(vm).unwrap()in theirrepr_str()implementations, which turned exceptions raised by the wrapped object's__repr__()into Rust panics.Since
repr_str()already returnsPyResult<String>, this change uses?to propagate the original Python exception unchanged, matching CPython's behavior.Testing
cargo run -- extra_tests/snippets/syntax_class.pyRegression tests were added for both descriptor types.
Before this change, both test cases triggered a Rust panic when the wrapped object's
__repr__()raised an exception.AI assistance
Codex (GPT-5.6 Sol) was used to investigate and implement this change.
I reviewed and validated all AI-assisted work.
