The linked sibling post on "New Truffle and GraalVM Languages release" feels rather exciting too https://medium.com/graalvm/new-truffle-and-graalvm-languages...

Specifically:

> GraalVM language runtimes (for JavaScript, Python, Ruby, Java on Truffle, WebAssembly, and LLVM) can now be [...] installed as Maven/Gradle dependencies [...] which will work for GraalVM JDK and any other compatible JDK

Polyglot experimentation just got a whole lot easier! Kudos to everyone involved in pushing the JVM ecosystem forwards.
