Ruby is awesome. We love its readability, flexibility, and developer-centric nature. Still, here at Mars, we also love Go because it has its own sense of simplicity and magic, too. Simply put, Go holds advantages over Ruby in some aspects: it’s faster, statically typed, and comes with cool concurrency primitives out of the box. This being said, some intrepid readers might find themselves grappling with a seemingly reasonable question: if Go is so darn good, why don’t we just write everything with it?

Read this tale and learn to write Go in Ruby, gaining the ability to modify Ruby exactly as you desire.
