Ruby 3.0
summary
Roadmap claims: three goals—and‑machine collaboration, performance and concurrency. Experiments show Ruby 1.9 gave roughly 2–3× speedup over 1.8 but took about five years to migrate; a tracing JIT sped benchmarks but “consumes lots of memory” and won’t fit small Heroku dynos so it’s shelved while IBM offers a method‑JIT alternative. Prototypes include soft typing via proactive warnings and a stream/pipeline operator and stream language as proofs of concept for safer, more concurrent Ruby.
