Andrew Svetlov 68b34a7204 bpo-36921: Deprecate @coroutine for sake of async def (GH-13346) 
The second attempt. Now deprecate `@coroutine` only, keep `yield from fut` as is.

Elvis Pranskevichus f9aeca2085 bpo-23859: Document that asyncio.wait() does not cancel its futures (#7217) 
Unlike `asyncio.wait_for()`, `asyncio.wait()` does not cancel the passed
futures when a timeout accurs.

Elvis Pranskevichus e2b340ab41 bpo-32751: Wait for task cancellation in asyncio.wait_for() (GH-7216) 
Currently, asyncio.wait_for(fut), upon reaching the timeout deadline,
cancels the future and returns immediately.  This is problematic for
when *fut* is a Task, because it will be left running for an arbitrary
amount of time.  This behavior is iself surprising and may lead to
related bugs such as the one described in bpo-33638:

    condition = asyncio.Condition()
    async with condition:
        await asyncio.wait_for(condition.wait(), timeout=0.5)

Currently, instead of raising a TimeoutError, the above code will fail
with `RuntimeError: cannot wait on un-acquired lock`, because
`__aexit__` is reached _before_ `condition.wait()` finishes its
cancellation and re-acquires the condition lock.

To resolve this, make `wait_for` await for the task cancellation.
The tradeoff here is that the `timeout` promise may be broken if the
task decides to handle its cancellation in a slow way.  This represents
a behavior change and should probably not be back-patched to 3.6 and
earlier.

Andrew Svetlov 4365b8302d Use asyncio.gather instead of asyncio.wait in example. 
gather will raise exception in case of problem but wait just returns done and pending lists of futures.
For getting error every future result should be retrieved, which is boring and error prone.
