> Test something with a throwing prototype getter and make sure the exception is rethrown

This is pretty hard to test without first failing the IsConstructor check. I think the following will work:

```js
const BadConstructor = new Proxy(function () { }, {
  construct() {
    return {};
  },
  get() {
    const e = new Error("should be rethrown");
    e.name = "rethrown";
    throw e;
  }
});
```
