    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).
