" summary

Scala Native now ships a continuations API (since 0.5) that implements loom-style fibers by saving activation frames and doing user-level context switching, and a dining philosophers demo runs many virtual threads across different workers showing the scheduler actually distributes work; JDK 24’s new single-word object header (22-bit class pointer) inspires reducing Scala Native’s mark-word overhead; Valhalla hints and Panama’s foreign/vector APIs are noted as paths for future low-overhead value types and native bindings. continuations API dining philosophers result JDK 24 object header
