Valhalla

Many features and changes we see coming live in new Java version (if not most of them) are developed under so-called umbrella projects. We frequently see syntax improvements from project Amber, project Jigsaw is about bringing modules, project Loom (surprise, surprise) is about new threads, project Panama roughly speaking is about using native stuff safely and efficiently, and among the most known ones, project Valhalla starts to become a thing, thanks to JEP-390 being included in Java 16.
