Actually, it should be considered as a bug, because calling `slice` on an `Object` should throw `TypeError: Object #<Object> has no method 'slice'`.

Are you aware of [Object.keys](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys)?

This is a sad day for the Node community. I hope someone will pick stylus soon!
