I played with it some time ago. Actually, original code <https://github.com/python/cpython/blob/master/Lib/contextlib.py> with few changes works fine. Here's example: https://gist.github.com/germn/6b2f8a1afbfc322daa01365cacd1d9ad Test it: import asyncio from acontextlib import acontextmanager state = [] @acontextmanager async def woohoo(): state.append(1) yield 42 state.append(999) async def main(): async with woohoo() as x: assert state == [1] assert x == 42 if __name__ == '__main__': loop = asyncio.get_event_loop() loop.run_until_complete(main()) 01.11.2016 19:15, Federico Marani пишет:

Has anyone tried to build an asynchronous version of @contextmanager? Is it even possible... given the use of yield?
