If I’m reading the latest spec draft correctly then
```js
class C extends null {
}
```
produces the following result:
1. Constructor kind: derived
2. Prototype of `C`: `Function.prototype`
3. Prototype of `C.prototype`: `null`
Neither #2 nor #3 seems very useful:
* #2 means that a super-constructor call is allowed but throws an exception,
because `Function.prototype` is not constructible. The default constructor will
perform a super-constructor call. As a result, you are forced to explicitly
return an object from the constructor if you don’t want an exception to be
thrown.
* #3 means that the constructor doesn’t even create objects whose prototype is
`null`, but objects whose prototype is an object whose prototype is `null`.
Therefore my question: is this useful for anything? Can’t `extends null` be
turned into something useful? Even treating `extends null` as equivalent to a
missing `extends` clause seems preferable.
Thanks!
