| ArrayBindingPattern : [ Elisionopt BindingRestElement ] |
| 1. If Elision is present, then |
| a. Let status be the result of performing |
| IteratorDestructuringAssignmentEvaluation of Elision with |
| iteratorRecord as the argument. |
| b. ReturnIfAbrupt(status). |
| 2. Return the result of performing IteratorBindingInitialization for |
| BindingRestElement with iteratorRecord and environment as arguments. |
