Keynote: Scala's Road Ahead
summary
Road map gives concrete milestones: Scala 2.12 requires Java 8 and ships JVM lambda and default-method support; Scala 2.13 focuses on simpler, modular collections and longer 2.11 maintenance; an experimental compiler Dotty implements the DOT calculus that after eight years proves type soundness and is already Dotty: 45,000 LOC, about 2x faster, using a TASTy whole-program format. Planned language changes include intersection/union types, trait parameters, safer lazy vals, replacement of old macros with scala.meta, implicit function types and an effect-capability model.
