And how would that method be implemented? Presumably the event loop would 
execute the coroutine, but that API is already there, and it's called 
create_task.  We will not be adding a builtin method for this.

You can use Task.add_done_callback() to add a callback.

[issue40844] Alternate ways of running coroutines

[Matthew Francis]

New submission from Matthew Francis <4576fran...@gmail.com>:

Currently, using await inside a coroutine will block inside the coroutine.  
This behavior would usually be fine, but for some usecases a way to 
nonblockingly run coroutines without creating a Task could be useful, because 
tasks don't allow for a callback.  I'm suggesting a method on coroutines that 
runs them without blocking, and will run a callback when it's complete.
