Panel On The Future Of Scala
summary
Overview of concrete progress and tradeoffs: Scala 3 (Dotty) keeps binary compatibility via tasty as a published artifact, tooling stays usable because semanticdb continues to power linters/refactors, and a new language server Metals language server already works for editing/navigation. Compilation work focuses on Hydra, which parallelizes per source file and records a real case of 20-minute builds reduced to 3.5 minutes (~6x). Typeclass proposals aim for coherence and multi-parameter support, and the roadmap removes fragile Scala 2 macros in favor of safer metaprogramming.
