There is a generic extension "markdown-everywhere", which can be configured to work for Clojure, so we get this:

But is has few issues, and need "settings to work with Clojure. I opened one issue:

I created an other issue
#3113 here
just before, which proposes an other way of combing markdown and clojure.
