    MemberExpression : new MemberExpression Arguments

    1. Return EvaluateNew(MemberExpression, Arguments).

    6. If arguments is empty, let argList be an empty List.
    7. Else,
       a. 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").
