I learned some cool new features coming in Ruby 2.7 and I am very much looking forward to them now.

The rest of this post is drivel, complaints, and ends with begging questions answered in his opening bullets. How does this optimize ruby for happiness? Flexibility and choice.

Backwards compatibility is maintained. You can write the same old ruby you wrote before if you want to avoid change. I'm very happy to have some new syntax tools in the toolbox.
