I had written a code contracts library for Ruby about 10 years ago [1]. I stopped working on it, mainly because it only provided runtime type checking, and I wanted static type checking. Nowadays my main language is typescript. I miss ruby, but can't give up the static typing that typescript provides. I really wish Ruby had a type system with the same level of support. VSCode has phenomenal TS support, and there's a community adding types to projects [2]. This is something I'd like for Ruby also.
> An integral part of this informality is relying on Matz’s taste and intuition for everything that affects the language’s core.
I think a more defined process would mean a better future for Ruby and Ruby developers.

> For myself, I'm fine with the typing being in a separate .rbs file
We type[0] by having one separate .rbs file per .rb file. Works really well with an editor's vertical splits: type outline on one side, code on the other. That, or use something like vim-projectionist[1].
