[Python-Dev] async generator bug fixed in 3.8+ and backported to 3.6 but not to 3.7

Hi, The fix for https://bugs.python.org/issue33786 ("@asynccontextmanager doesn't work well with async generators") was merged in 3.8 and then backported to 3.6. However, it was overlooked to be backported for 3.7 ( https://github.com/python/cpython/pull/7506). I'm aware that 3.7 is in security fix mode only so I'm not sure there's more to be done, however, given that this is fixed for 3.6, 3.7 is in a weird position still having the bug. So I just wanted to bring this up in case the fix can still be backported to 3.7. Matt
