description: Spread operator following other arguments when IteratorValue fails (SuperCall)
esid: sec-super-keyword-runtime-semantics-evaluation
features: [Symbol.iterator]
flags: [generated]
info: |
SuperCall : super Arguments
1. Let newTarget be GetNewTarget().
2. If newTarget is undefined, throw a ReferenceError exception.
3. Let func be GetSuperConstructor().
4. ReturnIfAbrupt(func).
5. Let argList be ArgumentListEvaluation of Arguments.
[...]
12.3.6.1 Runtime Semantics: ArgumentListEvaluation
ArgumentList : ArgumentList , ... AssignmentExpression
1. Let precedingArgs be the result of evaluating ArgumentList.
2. Let spreadRef be the result of evaluating AssignmentExpression.
3. Let iterator be GetIterator(GetValue(spreadRef) ).
4. ReturnIfAbrupt(iterator).
7.4.4 IteratorValue ( iterResult )
1. Assert: Type(iterResult) is Object.
2. Return Get(iterResult, "value").
7.3.1 Get (O, P)
[...]
3. Return O.[[Get]](P, O).
