For the longest time I was impressed by sophisticated/clever code that did hard things. As I built more and more systems I realized that such a perspective was futile that the better code in my mind was that which was clear, easy to read and understand the intent.
Any language changes whether they be core to the system or simply syntax sugar, any changes that make code more readable are by and large, good changes.
After reading keithwarren's comment I took a guess at what this operator might do and was delighted to see it confirmed in the article.
I would use this every day if it was available in the languages I use, specially in Javascript.
