[_pmf_]

Using Emacs' Elisp for a short while helped me unlearn some REPL antipatterns I acquired during Clojure development (some of them unfortunately presented in this article), especially this: instead of typing something in the REPL, executing it, then copying it back into your actual source file, you can just write it in your source file and use "evaluate current form" or "evaluate form before current point" to send it to the REPL process for evaluation instead of painstakingly entering it in the REPL and copying it back. Note that this is not a conventional hot-reload, but the form is sent as literal to the REPL (where indirectly, hot-reload may occur).
