+API Design and Implementation Note
+==================================
+
+Feedback on the initial beta release of Python 3.5 resulted in a redesign
+of the object model supporting this PEP to more clearly separate native
+coroutines from generators - rather than being a new kind of generator,
+native coroutines are now their own completely distinct type (implemented
+in [17]_).
+
+This change was implemented based primarily due to problems encountered
+attempting to integrate support for native coroutines into the Tornado web
+server (reported in [18]_).
