      Motor with Tornado currently requires:

      cursor = yield collection.aggregate(pipeline, cursor={})
while (yield cursor.fetch_next):
    doc = cursor.next_object()

      In asyncio, the same with "yield from". This should be possible instead:

      cursor = collection.aggregate(pipeline)
while (yield cursor.fetch_next):
    doc = cursor.next_object()

      Same in asyncio, again with "yield from".

      In Python 3.5, using asyncio or Tornado:

      async for doc in collection.aggregate(pipeline):
    pass
