> Too little too late, and I highly doubt that (5-year-old) Valhalla will deliver even one of the promised features (value types) in the next 3 years

I never understood the purpose of Valhalla. They should just introduce a 128-bit scalar type and call it a day. Nobody actually cares about automagically storing value types in HashMap — all interested parties (HFT, computing) have already written dedicated collection libraries for working with primitives, and those libraries have little in common with object-based ones.

pffft, hahahaha, no they don't.

JVM and LLVM don't even share same market niche — one is a feature-complete runtime, another is a "make-your-own-language" build kit. Webassembly? What webassembly?
