+    SpreadElement : ...AssignmentExpression
+
+    1. Let spreadRef be the result of evaluating AssignmentExpression.
+    2. Let spreadObj be ? GetValue(spreadRef).
+    3. Let iterator be ? GetIterator(spreadObj).
+    4. Repeat
+       a. Let next be ? IteratorStep(iterator).
+       b. If next is false, return nextIndex.
+       c. Let nextValue be ? IteratorValue(next).
+       d. Let status be CreateDataProperty(array, ToString(ToUint32(nextIndex)),
+          nextValue).
+       e. Assert: status is true.
+       f. Let nextIndex be nextIndex + 1.
