_low_type_ is early days still, but I think this approach is clearly the future of ruby typing. If this gets baked into the language for full “compile” time support and minimal performance impact, it will be amazing: https://github.com/low-rb/low_type

Previously, RBS-inline was the closest answer to typed Ruby, it was the JSDoc of Ruby. Recently, when I stumbled upon low_type and tried it out in irb, it finally felt like ”this is it, this is the TS of Ruby” and with runtime validation.

I like it, it deserves attention, especially for those who are seeking for typed Ruby. With this, you can finally experience it, and the syntax feels more ergonomic than with Sorbet.

It is definitely better than RBS and Sorbet. But unless Github / 37Signals or Shopify decide to use it, it is highly unlikely Ruby Core will consider it.

Out of all three I think Shopify have the highest possibilities. There may be additional usefulness interms of ZJIT.

This is so goergeous compared to the mess that's out there now.
