A few words on Ruby's type annotations state
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.

Why I Stopped Using Sorbet in All My Ruby Projects
Contracts gem can be a nice middle-ground. It has a fairly readably syntax and only checks method inputs and outputs at runtime. We use it to annotate important core methods, while leaving the rest type-free.

Should gems support old Ruby versions like 2.4?
For example contracts gem needs to have a separate version/branch for ruby 3.x due to the breaking change above

Cells - Introduction
This gives me access to input values as long as I defined them via attr_reader. Oh what's the Contract XXX above attr_reader? They are from contracts.ruby and completely optional and won't be explained in this post. You can safely ignore those and maybe study that gem later.
