Explicit iterator closing in response to error

5. Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).

6. If result is an abrupt completion, then
|
|
a. If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result).
|
|
b. IfAbruptRejectPromise(result, promiseCapability).
|
|
|
|
Runtime Semantics: PerformPromiseAny

8. Repeat

...
|

i. Let nextPromise be ? Call(promiseResolve, constructor, « nextValue »).
