- Add ITERABLE_COROUTINE (0x0100) to CodeFlags in bytecode.rs - Update frame.rs to check for both COROUTINE and ITERABLE_COROUTINE flags when validating 'yield from' on coroutine objects - Remove False and workaround in types.coroutine() now that the flag is supported - Remove @unittest.expectedFailure from test_async_def and test_genfunc Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Generators decorated with @types.coroutine have the CO_ITERABLE_COROUTINE flag set, making them awaitable. The GetAwaitable instruction now properly handles this case instead of only checking for __await__ method. This fixes the "object generator can't be used in 'await' expression" error that occurred with asyncio.sleep(0) which uses @types.coroutine decorated __sleep0() generator internally.

Generators decorated with @types.coroutine have the CO_ITERABLE_COROUTINE flag and can be used in await expressions. The PyAnextAwaitable's get_awaitable_iter method was missing this check, causing builtin anext() to fail with "object generator can't be used in 'await' expression" when used with such generators.

For generators without CO_ITERABLE_COROUTINE flag, try to get __await__ method instead of returning an error immediately. This matches CPython's _PyCoro_GetAwaitableIter behavior which allows generator subclasses that define __await__ to be used in await expressions.
