Description: Summary by CodeRabbit Refactor Call dispatch now prefers a vectorcall fast-path with internal fallbacks across calls, descriptors and types. New Features Added move-based argument handling to avoid unnecessary cloning during fast calls. Performance Lazier locals allocation and reduced argument copying for faster, lower-memory invocations. Bug Fixes Improved validation and clearer type errors for invalid method self-arguments.
