SpiderMonkey does not implement the (yet to be) spec'ed 
String.prototype.@@iterator function, instead it simply aliases 
String.prototype["@@iterator"] to Array.prototype["@@iterator"]:

js> String.prototype["@@iterator"] === Array.prototype["@@iterator"]
true

SpiderMonkey does not implement the (yet to be) spec'ed 
`String.prototype.@@iterator` function, instead it simply aliases 
`String.prototype["@@iterator"]` to `Array.prototype["@@iterator"]`:

```
js> String.prototype["@@iterator"] === Array.prototype["@@iterator"]

true
```
