YAML and YAMLScript
summary
YAMLScript is a new YAML-based loader and programming language that claims to give a single, consistent loader across languages, add embedded transforms, provide schema validation, and compile to native code. A reference implementation and libfyaml plus a PST-based release pipeline back the work; a playground shows 7 of 17 parsers fail (12/17 if the final newline is removed). Examples include a CircleCI config refactor done in ~30 commits that generates identical YAML, and a compiled runtime that boots in 19 ms startup versus ~4 s for raw JVM. YAMLScript loader aims for secure, reproducible loads.
