how would you do this tutorial with vim and fireplace? http://blog.cognitect.com/blog/2017/6/5/repl-debugging-no-stacktrace-required

I got stuck trying to change the exception:

(require '[clojure.main :as main])
    (main/repl :caught (fn [_] (println "Broken! HaHa!")))

vim froze up and I had to kill it

Fireplace is synchronous and it 'freezes' while doing nrepl operations..

oh, is main/repl kicking off a new repl

That makes sense

main/repl starts a new repl and grabs stdin, which makes the fireplace operation hang forever..
