Here is a list of useful REPL-related resources by the Clojure community:
In Running with Scissors: Live Coding with Data (slides here), Stuart Halloway presents his workflow for solving problems with the REPL, including little-known opportunities offered by the Clojure REPL without 3rd-party tools (such as custom reading). "You’re living in your program invoking your tools, instead of living in your tools invoking your program".
