I’d love to see more languages that could do this: Repl driven development (100x productivity boost, especially with immutability, fp and expression oriented language) Focus on data and data transformations (without classes, types and other clutter including syntax) Concurrency (from simple state management with atoms to CSP and STM) Libraries (this is where JVM really shines) Unfortunately I couldn’t find anything even close to Clojure.
