Scala Goes Native
summary
Announces an ahead‑of‑time Scala compiler and lightweight runtime that emit LLVM native binaries, add struct and stackalloc value types and allow manual allocation to avoid GC pressure. Demonstrates C++ at 7s, Scala Native at 8.7s vs 7s vs 15s for Java, with comparable memory use when allocations are manual. Provides extern C interop for calling C libraries, is currently single‑threaded, open source, targets x86_64 with ARM planned, and leaves unsafe pointer ops with undefined behavior.
