I want this but for Haskell :-) Maybe some of the amazing work on dataframe[0] and related libraries could be used for a better Haskell REPL in Emacs. I never much liked the notebook way of working, I prefer having a file of functions alongside a REPL, but time-to-graph is bad, and I don't know if there's a good solution to how the REPL forgets previously defined variables on reloading a file.

Bruh can we make emacs, let alone cider, let alone "julia snail", more usable before we brag about achieving something? It's extremely embarrassing how sloppy the emacs experience has gotten in the last thirty years relative to other environments.
