It's confusing how 'REPL' refers to two different UIs: A CLI like IPython or Julia, where things like multiline editing and syntax highlighting need careful implementation. An editor protocol like SLIME or CIDER where multiline editing is a total non-issue.

There's something of a tradition of REPLs having personalities in lisp. I've seen Common Lisp tools (e.g. slime/sly) and Clojure (e.g. cider) say encouraging things, but Fennel is almost judgemental :)

I am regularly impressed with Cider. Today I'm digging the friendly, unobtrusive UI for step debugging.
