SpreadElement : ...AssignmentExpression
1. Let spreadRef be the result of evaluating AssignmentExpression.
2. Let spreadObj be ? GetValue(spreadRef).
3. Let iterator be ? GetIterator(spreadObj).
4. Repeat
a. Let next be ? IteratorStep(iterator).
b. If next is false, return nextIndex.
c. Let nextValue be ? IteratorValue(next).
d. Let status be CreateDataProperty(array, ToString(ToUint32(nextIndex)),
nextValue).
e. Assert: status is true.
f. Let nextIndex be nextIndex + 1.
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).
