The ``[[clang::coro_await_elidable]]`` is a class attribute which can be
applied
to a coroutine return type.
-When a coroutine function that returns such a type calls another coroutine
function,
-the compiler performs heap allocation elision when the call to the coroutine
function
-is immediately co_awaited as a prvalue. In this case, the coroutine frame for
the
-callee will be a local variable within the enclosing braces in the caller's
stack
-frame. And the local variable, like other variables in coroutines, may be
collected
-into the coroutine frame, which may be allocated on the heap.
+When a coroutine function returns such a type, a direct call expression therein
+that returns a prvalue of a type attributed ``[[clang::coro_await_elidable]]``
+is said to be under a safe elide context if one of the following is true:
+- it is the immediate right-hand side operand to a co_await expression.
+- it is an argument to a [[clang::coro_must_await]] parameter or parameter pack
