Keynote: Beyond Ruby3.0
summary
Ruby 3.0 ships concrete features not promises: RBS and TypeProf enable static typing via external signatures and abstract interpretation rather than language syntax, third‑party checkers feed IDE completion, Ractors (actor model) bring isolated parallelism with limited shared immutable objects and channels, new syntax like pattern matching and numbered block params shortens code, and performance pushes continue with a 3x3 performance goal and multi‑layer JIT (yjit integration) aiming to make some workloads several times faster.
