desc: Spread operator applied to the only argument when IteratorValue fails
template: error
features: [Symbol.iterator]
info: |
12.3.6.1 Runtime Semantics: ArgumentListEvaluation
ArgumentList : ... AssignmentExpression
1. Let list be an empty List.
2. Let spreadRef be the result of evaluating AssignmentExpression.
3. Let spreadObj be GetValue(spreadRef).
4. Let iterator be GetIterator(spreadObj).
5. ReturnIfAbrupt(iterator).
6. Repeat
a. Let next be IteratorStep(iterator).
b. ReturnIfAbrupt(next).
c. If next is false, return list.
d. Let nextArg be IteratorValue(next).
e. ReturnIfAbrupt(nextArg).
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).
