| Error when accessing an iterator result's `value` property (rejecting |
| promise) |
| info: | |
| Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability). |
| If result is an abrupt completion, then |
| If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result). |
| IfAbruptRejectPromise(result, promiseCapability). |
| |
| ... |
| |
| Runtime Semantics: PerformPromiseAny |
| |
| ... |
| Repeat |
| Let nextValue be IteratorValue(next). |
| If nextValue is an abrupt completion, set iteratorRecord.[[Done]] to true. |
| ReturnIfAbrupt(nextValue). |
