I got a prototype working which drops the user into a REPL whenever an error occurs during evaluation, including making everything in the current environment available in scope! https://asciinema.org/a/g6jOg0tgtgLMMzyffdOZKUB4r

Python already has this, and you can hook up IPython with pdb to get a fancy REPL on error.
It's called postmortem debugging
