The idea is that you do most of your work using a REPL. The typical workflow for Clojure is to start the app once and work with it interactively.
Clojure editors have tight integration with the REPL, so you can send any code from the editor to be evaluated in the context of the running application image.
While stacktraces are long, the relevant information tends to be easy to identify. In most cases you just look for a the first occurrence of a namespace from your project and trace from there. There also tools for making reading stack traces easier such as https://github.com/venantius/ultra and https://github.com/magnars/prone
