+The ``[[clang::coro_await_suspend_destroy]]`` attribute applies to an
+``await_suspend(std::coroutine_handle<Promise>)`` member function of a
+coroutine awaiter. When applied, suspensions into the awaiter use an optimized
+call path that bypasses standard suspend intrinsics, and immediately destroys
+the suspending coro.
+
+Each annotated ``await_suspend`` member must contain a compatibility stub:

+.. code-block:: c++
+
+ [[clang::coro_await_suspend_destroy]]
+ void await_suspend(std::coroutine_handle<Promise> handle) {
+ await_suspend_destroy(handle.promise());
+ handle.destroy();

What does it mean? Does it say the function must be implemented as is? If yes,
I feel bad for that. I prefer the previous design.
