This is probably the best blog post I've seen on the topic: https://vvvvalvalval.github.io/posts/what-makes-a-good-repl.html https://vvvvalvalval.github.io/posts/what-makes-a-good-repl.... > If you're not familiar with Clojure, you may be surprised that I describe the REPL as Clojure's most differentiating feature: after all, most industrial programming languages come with REPLs or 'shells' these days (including Python, Ruby, Javascript, PHP, Scala, Haskell, ...). However, I've never managed to reproduced the productive REPL workflow I had in Clojure with those languages; the truth is that not all REPLs are created equal. Basically, the "REPL" you usually call a REPL is in fact a shell, and not a REPL as normally used in lisp languages.
