Thanks for the tip.  I primarily use it for the minification benefit when `this` is used multiple times inside a function, but perhaps it's better to leave as `this`.  So in [this ScrollView example](https://github.com/derek/yui3/blob/master/src/scrollview/js/scrollview-base.js#L129), you'd still recommend `this` vs `sv`?

This specific instance will be removed anyways, as you'll see from the line 41 comment.
