+1. The big win of arrow-functions, is that it prevents from using various
ad-hoc kludges (`var that = this`, `[].some(..., this)`, etc), whose sole goal
is to defeat some unwanted feature (proper `this` binding in callbacks). Not a
killing-feature, but a nice addition that will help to reduce noise in code.
