and why that better than:
```js
function add(a,b) {return a+b}
add(2,3);
```
Every new feature increases the conceptual complexity of a language and to
justify that it needs to provide a big pay back. This doesn't seem to have
much of a pay back. Adding the & and :: doesn't eliminate the need for JS
programmer to learn about `this` in functions for the various already existing
ways to call a function with an explicit `this` value. It just add more new
syntax that needs to be learned and remembered are move feature interactions
that have to be understood.
JS doesn't need more syntax and semantics piled on to `this`. Ideally some
would be taken away. However, the latter is not possible.
