Beartype 0.7.1

on Python PyPI

This release delivers eleventh-hour support for the NotImplemented singleton and improved compliance with static analysis tooling like static type-checkers (e.g., mypy) and intelligent IDEs (e.g., not Vim). This release resolves 4 outstanding issues and merges 1 pending pull request.

Changes include:

Compatibility Improved

• NotImplemented singleton. @beartype now explicitly supports the builtin NotImplemented singleton with the same behaviour implemented by mypy to support this singleton, resolving issue #38 kindly reported by Matt the positive @posita. Specifically, @beartype now implicitly coerces binary dunder methods (e.g., __eq__()) annotated as returning booleans to instead be annotated as returning either booleans or the NotImplemented singleton (e.g., from def __eq__(self, other: object) -> bool to def __eq__(self, other: object) -> Union[bool, type(NotImplemented)]).
• Static analysis. @beartype now better complies with static analysis performed by both static type-checkers (e.g., mypy) and intelligent IDEs (e.g., not Vim), resolving both issues #36 (kindly reported by @jonathanmorley the majestic code maestro) and #39 (again kindly reported by Matt the positive @posita). Specifically, the @beartype decorator itself is now annotated as returning a callable having the exact same signature as the passed callable. Previously, @beartype was annotated as merely returning a callable of arbitrary signature. Thanks again to @jonathanmorley the majestic code maestro for both the initial issue and pull request resolving that issue!
