ah yes, this is because primitive math relies on a Java class which is not in bb:

Unable to resolve classname: primitive_math.Primitives

@U05AJ7KNDGE I translated https://www.baeldung.com/java-uuid Java to Clojure and it worked: https://gist.github.com/borkdude/18b18232c00c2e2af2286d8bd36082d7

$ bb /tmp/uuidv1.clj
#uuid "98217366-018a-1000-b164-f4689455adbf"

Thanks a lot, Michiel

probably it's easier to transform the result yourself using camel-snake-kebab afterwards

You do have a point.
