Seems like a typo and Tab’s got it right. The advantage of a thin arrow (over a method definition) here is that you can do an implicit return and have slightly less to type. Given that method definitions don’t appear inside statements, I don’t see that as a problem.
AFAIK, an implicit return of the completion value of a method is out, because one might involuntary return wrong values (previously: undefined, now: completion value).
