Very nice.

This is great, but after 5 years, some things have changed in Clojure tools, see the warnings:

$ clojure -Sdeps '{:deps {hello-clojure {:git/url "https://gist.github.com/athos/b68b15b08efedffaf14d8c020b125202" :sha "1c9a05106171f97f9b8e8ac8f58c7bd8dbe021f9"}}}' -m hello-clojure

WARNING: Implicit use of clojure.main with options is deprecated, use -M

Those warnings are not a big deal, but I've added some updates to fix them.
