Sorry, I'm having hard time believing that. I don't know when was the last time you've used the language, but today there are so many different ways to easily see and analyze the data you're dealing with in Clojure - there are tons of ways in CIDER, if you don't use Emacs - there are numerous ways of doing it in Calva (VSCode) and Cursive (IntelliJ), even Sublime. There are tools Like Portal, immensely capable debuggers like Flowstorm, etc. You can visualize the data, slice it, dice it, group it and sort it - all interactively, with extreme ease.
I'm glad you've found great fondness for Elixir, it is, indeed a great language - hugely inspired by Clojure btw.
You still don't need to bash other tools for no good reason. It really does sound fake - not a single Clojure developer, after using it for more than a decade, would call a Lisp REPL "a band-aid and not a solution". It smells more like someone with no idea of how the tool actually works.
