You can just ignore the rule before that via sth like:
```js
if ( hasRaf ) {
    /* jshint undef: false */
    window.cancelAnimationFrame( timerId );
    /* jshint undef: true */
} else {
```
instead of using `window.cancelAnimationFrame` directly. At least the comments will go away after minification.

But maybe the release can happen soon... @rwaldron, can you ask @valueof to release a new patch version?
