> This has been fixed in 3.4.2, but shows up in the 3.4.1 documentation.

Well, I didn't want to change Python 3.4.1 documentation, but it looks like https://docs.python.org/3.4/ is updated after each commit into the 3.4 branch. For example, new asyncio functions added in 3.4.2 are already documented:

https://docs.python.org/3.4/library/asyncio-eventloop.html#asyncio.BaseEventLoop.create_task

I changeed all examples to use create_task() instaed of async() or the Task contructor:

Update asyncio documentation

- Document the new create_task() method
- "Hide" the Task class: point to the create_task() method for interoperability
- Rewrite the documentation of the Task class
- Document the "Pending task destroyed"
- Update output in debug mode of examples in the dev section
- Replace Task() with create_task() in examples


Maybe I should revert this change in the 3.4 branch, but mention that Python 3.4.2 and 3.5 have a new create_task() which is now the recommanded way to schedule a coroutine (to create a task object).
