Walkthrough

The changes update exception handling by refining the initialization logic for SyntaxError, ImportError, and UnicodeDecodeError in the Rust backend, ensuring correct attribute setup and keyword validation. Corresponding Python tests have had the @unittest.expectedFailure decorators removed from multiple methods, reflecting improved compatibility or correctness in the implementation. Additionally, developer instructions were strengthened to mandate running Clippy with fixes.

Changes

File(s) Change Summary
Lib/test/test_exceptions.py, Lib/test/test_traceback.py Removed @unittest.expectedFailure decorators and related TODO comments from eight test methods.
vm/src/exceptions.rs Modified slot_init for PyImportError to validate keywords; added slot_init for PySyntaxError with tuple unpacking; updated PyUnicodeDecodeError to set object as bytes.
.github/copilot-instructions.md Strengthened instructions to always run Clippy and fix warnings before completing tasks.

Poem

A hop and a leap, the tests now pass,
Syntax and bytes, handled with class.
ImportError’s keywords checked with care,
No more failures hanging in the air!
Clippy’s warnings fixed with might,
The rabbit hops—code shining bright! 🐇✨
