It's an example of that particular social more and the canonical example of good vs. bad looping over an array. That's why I used it.

  I see your concern, if I was a beginner and I googled around I might be inclined to learn the supposedly good looping which might be difficult.

    Oh, no concern at all about the ruby style guide. I even point people at it in the book so they can start grasping and writing code with other people. My mention of the guide is not intended as a knock on the guide at all.

      Got it. Thanks for the clarification.
