Thanks for the suggestions! Daniel's code helped me a lot, thanks!
One thing that had me stuck for a while is that you have to have a Clojure
jar in your classpath. I also worked through a different way, using an
uberjar of a Clojure project. I posted my guides here
<https://push-language.hampshire.edu/t/calling-clojure-code-from-java/865?u=thelmuth>
for anyone else trying to do this.
