| 1. Let rhs be the result of evaluating Initializer. |
| 2. Let value be GetValue(rhs). |
| 3. ReturnIfAbrupt(value). |
| 4. Let env be the running execution context's LexicalEnvironment. |
| 5. Return the result of performing BindingInitialization for BindingPattern |
| using value and env as the arguments. |

| 2. If iteratorRecord.[[done]] is true, let v be undefined. |
| 3. If Initializer is present and v is undefined, then |
