RBS, Ruby’s new type signature language

I'm still trying to make sense of this announcement. With a lack of type annotation in the Ruby core, I chose to build off YARD to make gradual type safety work. Now I don't know if there will be a standard that supports type safety or if I should continue down the path I'm already following. Help me, Ruby core developers. You're my only hope.

(edit: I should have explained that I'm talking about the type checking features I'm developing in Solargraph: https://solargraph.org/guides/type-checking)

I hear you. It occurred to me that Ruby could have chosen to innovate with something like a Semantic TomDoc. To choose a separate file based approach seems like a step backward. At the very least it could have been module based. But Matz is a C coder -- not a Ruby coder. So it doesn't necessarily surprise me.

It's sad though. Since poor design of Refinements, C transpiling for 3x project, and now this, I am less and less inclined to continue using Ruby. I miss some of the dynamics but I find myself using Crystal instead.

(Honestly, if any one figured out a way to supplement Crystal with dynamic behavior for those features that a static language can't offer, Ruby would be done.)
