Just dropping in real quick to correct a couple things.
First, `arguments` itself is *not* deprecated in strict mode. Things
like `arguments.caller` are deprecated and throw a `TypeError` when
the corresponding function is in strict mode.
Second, some of you all were looking to use `Object.assign` to help
explain. You'd need to do this for it to be correct:
```js
class C {
constructor(a, b, ..., y, z) {
Object.assign(this, {a, b, ..., y, z})
}
}
```
(Not TC39, just I felt the need to correct people here.)
