I like [`Hash#fetch`](http://www.ruby-doc.org/core-1.9.3/Hash.html#method-i-fetch) because I feel that it's a little more intention-revealing than the more commonly used `hash[hey] || other` pattern. This isn't a case that's exceptional enough to raise so the `x || y` pattern is fine here, but I just like `fetch` these days :) I'd be happy to change it if you'd like.
