That's funny, I didn't need it when I wrote the Coherent MVC library. There's
no explicit call to update the UI, it's all achieved through the magic
available in ES3. ES3! Not the goodness of ES5. (After all, it still has to
work in IE.)

Now, you'll only be able to detect changes to raw properties on ES5 browsers,
because IE doesn't support getters and setters, yet. But if you're willing to
recraft your code to look like the following:
model.doStuff();
model.setX(model.getX()+1);
You'll be just fine on ES3 browsers.
