EcmaScript Proposal - Promised functions

[Naveen Chawla]

I'd prefer a "new Promise" literal analogous to {} for objects and '' for
strings:

```js
p\
    resolve=>
        setTimeout(
            resolve,
            forHowLong)
\
```

I think the "this.resolve" proposal wouldn't work for methods, for example.
