📝 Walkthrough

Walkthrough

Introduces comprehensive Python object protocol implementation in the VM with optimized rich comparison short-circuiting for identical objects, alongside extensive new methods for attribute management, iteration, type checking, subscripting, comparison, and representation across PyObjectRef and PyObject.

Changes

Cohort / File(s)	Summary
Comparison and Boolean Semantics `vm/src/protocol/object.rs`	Added `rich_compare()`, `rich_compare_bool()` with identity-based short-circuit optimization for Eq/Ne operations, plus `is_true()`, `not()` for truthiness evaluation
Attribute Protocol `vm/src/protocol/object.rs`	Implemented full attribute management via `get_attr()`, `set_attr()`, `del_attr()`, `has_attr()`, `get_attr_inner()`, `call_set_attr()`, `generic_getattr()`, `generic_getattr_opt()` with descriptor protocol and fallback handling
Iteration and Length `vm/src/protocol/object.rs`	Added `get_iter()`, `get_aiter()` for iteration, `length()`, `length_opt()`, `length_hint()` for size queries, and `dir()` for attribute enumeration
Subscripting and Containment `vm/src/protocol/object.rs`	Introduced `get_item()`, `set_item()`, `del_item()` for mapping/sequence protocol operations
Type and Instance Checking `vm/src/protocol/object.rs`	Implemented `obj_type()`, `type_check()` for type introspection and subclass/instance validation
Representation and Conversion `vm/src/protocol/object.rs`	Added `repr()`, `ascii()`, `bytes()` for object stringification and data conversion

Poem

🐰 A protocol so grand, with objects at hand,
Comparisons swift when they're the same,
Attributes found, iteration around,
The VM's now richer in every way! ✨

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title mentions fixing a test error in test_dictviews.py from object.rs, which aligns with the small optimization in rich_compare_bool but significantly underrepresents the extensive object protocol implementation comprising the bulk of changes.	Update the title to reflect the primary change: comprehensive Python object protocol implementation with rich comparisons, attribute management, iteration, and error handling across PyObjectRef and PyObject.
Docstring Coverage	⚠️ Warning	Docstring coverage is 37.84% which is insufficient. The required threshold is 80.00%.	You can run `@coderabbitai generate docstrings` to improve docstring coverage.
