Tracing debuggers give you the best of both worlds. I've recently started using Flow-storm [0], by @jpmonettas), and it's been quite transformative. You can still easily see the values flowing through your system (better than just "prints"), and it can handle multi-threaded / async scenarios quite nicely. You don't need to manually step through code, you can just "see" your data flow, and when you have loops or some other form of iteration, you can see the data for each pass. Coupling this with a good data visualization tool (such as Portal [1]) really feels like magic. I've been doing Clojure for quite a few years now, and was very happy with my plain REPL-driven workflow, but this is way better.
