+description: Invocation of iterator `return` method
+info: |
+  YieldExpression : yield * AssignmentExpression
+
+  1. Let exprRef be the result of evaluating AssignmentExpression.
+  2. Let value be ? GetValue(exprRef).
+  3. Let iterator be ? GetIterator(value).
+  4. Let received be NormalCompletion(undefined).
+  5. Repeat
+     a. If received.[[Type]] is normal, then
+        [...]
+     b. Else if received.[[Type]] is throw, then
+        [...]
+     c. Else,
+        i. Assert: received.[[Type]] is return.
+        ii. Let return be ? GetMethod(iterator, "return").
+        iii. If return is undefined, return Completion(received).
+        iv. Let innerReturnResult be ? Call(return, iterator, «
+            received.[[Value]] »).
+        [...]
