 model of asynchronous programming in Python and make it as close to
 synchronous programming as possible.
 
+This PEP assumes that the asynchronous tasks are scheduled and
+coordinated by an Event Loop similar to that of stdlib module
+``asyncio.events.AbstractEventLoop``.  While the PEP is not tied to any
+specific Event Loop implementation, it is relevant only to the kind of
+coroutine that uses "yield" as a signal to the scheduler, indicating
+that the coroutine will be waiting until an event (such as IO) is
+completed.

 We believe that the changes proposed here will help keep Python
 relevant and competitive in a quickly growing area of asynchronous
 programming, as many other languages have adopted, or are planning to
