New submission from Mathias Fröjdman:
Since asyncio event loops have to be closed nowadays, it would be pretty
convenient and pythonic to make BaseEventLoop a context manager that calls
self.close() in __exit__ the same way as contextlib.closing() does it. Example:
import asyncio
with asyncio.get_event_loop() as loop:
loop.run_until_complete(func())
instead of
import asyncio
from contextlib import closing
with closing(asyncio.get_event_loop()) as loop:
loop.run_until_complete(func())
or event the bulkier
import asyncio
loop = asyncio.get_event_loop()
try:
loop.run_until_complete(func())
finally:
loop.close()
The attached patch applies to Python 3.5b4's asyncio/base_events.py
