 Creating a task automatically schedules it for execution (by adding a
 callback to run it in the event loop's to-do list, that is, collection of jobs).

+:mod:`!asyncio` automatically associates tasks with the event loop for you.
+This automatic association was purposely designed into :mod:`!asyncio` for

+Without it, you'd have to keep track of the event loop object and pass it to
