================
Comment at: test/SemaCXX/coroutines.cpp:842
+struct bad_await_suspend_return {
+  bool await_ready();
+  // expected-error at +1 {{the return type of 'await_suspend' is required to be 'void' or 'bool' (have 'char')}}
----------------
For test completeness, I would have a positive case for something like a std::true_type returning await_ready
