The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

Your one line solution is elegant. In general, I think shorter programs are better. But sometimes, really short code is harder to maintain, since you have to grok all the cool functions. So it requires better developers.
I look at similar examples in scala, and it takes a while to figure out what the elegant code does.
