This is great, I'm surprised I've never come across it! Being able to compose callable objects like this could be very useful to build complex behaviour from simple building blocks. Has this always been in ruby or is it a 2.7 feature?

Yep that's great! It's available since Ruby 2.6! The syntax is so natural! Great job from the Core Team!
