I actually did that at first, but then `@subject` was lost, because [`this` gets set to `undefined`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach). I thought that, rather than working around this by passing in context, this syntax would be more readable.

I'm new to Coffeescript; is there a better way to deal with this issue while still keeping the loop clean?
