RBS, Ruby’s new type signature language

I absolutely hate this.

Separate files for types with no inline annotations possible? What an embarrassing compromise. This is all because Matz explicitly won't allow type signatures in .rb files. I wonder how long it'll be until a hostile fork if he doesn't change his mind.

I wouldn’t call it “embarrassing.” What is the actual benefit of having inline type annotations? What is the actual downside of having them in a separate file?

The benefit is being able to see what type a variable is without having to open a separate file. Having an option to also have them in a separate file (ala TypeScript) is perfectly fine
