I usually agree with anything Phlip says, but not on this :)

I love that ruby has the unless keyword and use it often.  IMO the
version with unless above reads just fine and you should go with
whichever reads better for you.

No need to open up a conversation about unless vs. if !, particularly
since it's happened before [1].  Just wanted Brad to hear an
alternative opinion.
