You can absolutely run an nREPL server from a mostly-Java application.
Something like this would do (just a sketch, untested):
private static IFn startServer, stopServer;

require).invoke(Symbol.intern(clojure.tools.nrepl.server));

Hi,
While you don't need to know all about Java the language to use Clojure,
you DO need to learn about the standard Java APIs for things like I/O,
networking, GUIs, etc. Clojure doesn't try to hide those features of the
host platform (whether in Java, C#, or JavaScript). There are great

No; just add a (:require foo.recs) to the ns form of foo.prots, so the

avoid any ahead-of-time compilation.
In general, AOT is rarely necessary, and almost always a hinderance.

Java is not a barrier of entry for Clojure for most folks - it is in fact
one of the major reasons for Clojure's success. If you're mostly
interesting in GUIs and games - some people have taken the time to provide
Clojure-y libraries for just that.
