Anyone got any experience with GraalPy? https://www.graalvm.org/latest/reference-manual/python/

"Python 3.10 compliant runtime" claiming a 3-4x performance boost over cPython once the JIT has warmed up

It's under Oracle's Universal Permissive License which looks GPL-like, and apparently has OSI approval https://opensource.org/license/upl/

I'm interested in it primarily because it might provide a robust option for running untrusted Python code in a sandbox (still a perennial research question for me) https://www.graalvm.org/latest/security-guide/polyglot-sandbox/
