This is really nice. lastIndex silliness in ES5 has bitten me quite a few times, and the example code shows how much better this would be. I hope someone on TC39 wants to champion this!

Well, obviously it doesn’t make much sense to do that for `text()`, but it would be great to have for `exec()`.

At the moment, the following two methods abuse regular expressions as iterators (if the /g flag is set):

* `RegExp.prototype.test()`
* `RegExp.prototype.exec()`

Would it make sense to create similar methods that return something iterable, so that for-of can iterate over the result?
