Concise Method Binding

[JD Isaacks]

I think what you are suggesting already exists with `::obj.method` which
evaluates to `obj.method.bind(obj)`

However, this creates a new function each time so `::obj.method
!== ::obj.method`, not sure how `::obj.method === ::obj.method` would work.

I sort of agree with you that using it that way would be preferred. However
if the community wants bound methods attached to objects, there is
currently no way to do that with an object literal.

You would have to do something like:

```
let obj = {};
obj.method = function(){}.bind(obj);
```

With my proposal you can.

```
let obj = { ::method(){} };
```
