Just doesn't cut it... Give me python 3 style typing at the least. Nobody wants external file decorators.

I'd love to have Python3 style typings in Ruby, but I think they refused the idea because backwards compatibility?

I think the closest gem that achieves this is contracts. https://github.com/egonSchiele/contracts.ruby?tab=readme-ov-...

Sorbet can be used inline without external file decorators already and RBS is adding support too[2].

I would not be surprised if that typing information starts finding its way into YJIT for performance improvements.
