Arrays in Ruby Discussion

Yes! I love that one! :)

I forget about it all the time. Nice to get the reminder! : )

agreed, but what scenario would we use this in?

Any scenario where you want to forgot to save the last thing returned in your console or IRB session to a variable. You can also call methods on _ and they will be sent to whatever the last returned object/result was from your console session.

Indeed, I very much agree with you
