[New-bugs-announce] [issue26159] Unsafe to BaseEventLoop.set_debug(False) when PYTHONASYNCIODEBUG=1

[Bradley McLean]

New submission from Bradley McLean:

Leads to spurious RuntimeWarning: coroutine  was never awaited messages, when @asyncio.coroutine methods call async def methods.  Likely because decorators ran before set_debug set False, and are assuming it won't change.
