yes this is the correct way, this IS repl-driven development.. The REPL is a entrypoint into the world of the running program, and ideally the editor is connected to the program via the REPL, but you still write code in the editor. Most Lisp beginner tutorials - the ones that don't start with teaching emacs - will ask the reader to just paste code into the REPL. This sets up bad habits... Perhaps we'll have better AND easier tutorials one day.
