You may try out using Scala as script language like this: "scala myScript.scala". The first startup times are slower, and even after that it may be slower than Python/Ruby but it still may be sufficient for your use case.

Using "sbt ~run" (re-runs your program automatically at every file change) may also be an option.

I don't see a reason why Clojure couldn't achieve the same startup time? I am trying to avoid the JVM startup time itself so that leaves out Scala/Clojure.

I'd like to be able to have a fast startup time when, say, running a script with its containerized environnement, when it is done the container exits, so I can't leave a vm running.

So I believe that leaves out JVM languages.

Independently from that, I did try Scala before Clojure and found its grammar to be overkill and unintuitive so it wouldn't be my first choice.
