+Subject: [PATCH 1/2] Don't use asyncio.coroutinefunction if it's not available
+
+Python 3.11 drops the deprecated @asyncio.coroutine and
+asyncio.iscoroutinefunction.
+
+Using a wrapper with @asyncio.coroutine in __get__ wasn't
+necessary (the future from asyncio.ensure_future is awaitable,
+and the wrapper doesn't do anything asynchronous), so the
+logic can be simplified to just call asyncio.ensure_future
+(to schedule the task and store the result when it's
+available).
+
+Tests for @asyncio.coroutine are skipped on 3.11+.
+
+An unnecessary call to asyncio.coroutine in tests is
+removed: it's not necessary to call this for `async def`
+functions.
