Python 3.15: 헤드라인을 장식하지 못한 기능들

Python 3.15 introduces practical but underappreciated improvements to asyncio, context managers, and threading that streamline concurrent programming patterns. TaskGroup.cancel() eliminates boilerplate exception handling for graceful cancellation, while ContextDecorator now properly wraps async functions and generators, solving a longstanding footgun in decorator usage. These refinements reflect Python's sustained commitment to making async/concurrent development more intuitive and less error-prone for mainstream developers.
