| The IsConstructor(ctor) happens after evaluating the arguments, use the correct ctor |

| NewExpression : new NewExpression |
| 1. Return ? EvaluateNew(NewExpression, empty). |
| MemberExpression : new MemberExpression Arguments |
| 1. Return ? EvaluateNew(MemberExpression, Arguments). |

| Runtime Semantics: EvaluateNew |
| |
| 3. Let ref be the result of evaluating constructExpr. |
| 4. Let constructor be ? GetValue(ref). |
| 5. If arguments is empty, let argList be a new empty List. |
| 6. Else, |
| a. Let argList be ? ArgumentListEvaluation of arguments. |
| 7. If IsConstructor(constructor) is false, throw a TypeError exception. |
| 8. Return ? Construct(constructor, argList). |
