I see that in step 13 of the [[Construct]] method of ordinary functions (
https://tc39.github.io/ecma262/#sec-ecmascript-function-objects-construct-argumentslist-newtarget),
the value resulted from the evaluation of the function body is checked and
if the constructor is a derived constructor, the value cannot be a
primitive different from undefined. Why isn't the same check performed if
the constructor is a base constructor?
Example of code that, when executed in the Chrome console, throws:
```
(function () {
'use strict';
class A {
constructor() {
return 4;
}
}
class B extends A {
constructor() {
super();
return 2;
}
}
new B();
})();
```
