Ruby3 Typing, 2020

Recall the Matz's keynote in 2016, Ruby3 Typing. It was three years ago and everything started. We build a team. We had a lot of discussions and wrote code. We discovered things that changed the original plan. Now we have a set of conclusions for type checking in Ruby3.

It's time to see how our effort lands.
