@kalabiyau, we should be able to add that to the rubocop: https://github.com/bbatsov/rubocop/blob/master/config/enabled.yml#L188

I haven't looked at the rubocop config in a while, but it might be worth a second pass, especially with your keen sense of style ;)  

Last time I made changes, and had to go through and update a bunch of files to get them passing, but easy commits.
