I'm hoping the hard-copy REPL will make a resurgence within the hipster community: https://www.youtube.com/watch?v=_DTpQ4Kk2wA
Using one of the old ones is a bit of a hassle since they are big and difficult to maintain.
If there was a more modern one I'd buy one.
@ebarrett Funky. But the first time I saw how Emacs, SLIME and SBCL work together, I was blown away by it. And now you can connect to the node REPL from Emacs as well. Pretty cool stuff.
