Walkthrough

The changes update bytes and bytearray construction logic and tests. The test for constructor exceptions is no longer marked as an expected failure. The Rust implementation now tries calling __index__ on the source object first, propagates exceptions properly, centralizes fallback handling for other types, and creates type errors explicitly via the VM.

Changes

File(s) Change Summary
Lib/test/test_bytes.py Removed @unittest.expectedFailure decorator and preceding comment from test_constructor_exceptions in BaseBytesTest.
vm/src/bytes_inner.rs Added handle_object_fallback method; modified get_bytearray_inner to prioritize __index__, propagate exceptions, and unify error handling with explicit VM type errors.

Poem

In the warren of bytes, a new path appears,
Exceptions now bubble, no longer masked by fears.
The test stands tall, no expected fail,
While Rusty logic follows the bunny trail.
With errors unified, and surprises in store,
Rabbit devs hop on, bytes magic galore! 🐇✨
