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.
