Ah thanks, I was trying to remember Lighttable; there must be emacs plugins for CL for that I guess? As some type of more addition to the REPL functionality; having it more automated?
AFAIK it doesn't have any sort of extension like this though. But maybe someone with more CL experience can advise! Hopefully someone has a better idea for you :)
I see the stuff in the parent post but not sure exactly what it can do vs what I envision or you may be picturing...
