Keynote and Q&A: Matz
summary
Announces concrete Ruby 2.3 additions — frozen string pragma, safe-navigation and lonely operators, dig, hash comparisons and hash_to_proc, plus bundling the juma typo-suggestion gem — and reports steady 5–10% yearly speedups and a released 2.3. States an explicit performance target: Ruby 3x3 goal (3× faster than 2.0) and explores concurrency designs (ownership model, actor/stream pipelines, skeptical take on STM), MRuby progress, and asks for C contributors and sponsor help; gives enough specifics and numbers to judge technical payoff.
