It makes me think of Lem's `watch` that displays s-expr results in an overlay, much like CIDER's Enlighten, somewhat like LightTable: https://lem-project.github

It makes me think of Lem's `watch` that displays s-expr results in an overlay, much like CIDER's Enlighten, somewhat like LightTable: https://lem-project.github.io/usage/common_lisp/#watch https://lem-project.github.io/usage/common_lisp/#watch There's sly-overlay too: https://git.sr.ht/~fosskers/sly-overlay https://git.sr.ht/~fosskers/sly-overlay (a couple function changes away to have it on Slime) but those are not inside the stepper. (edit) oh, there's Sly-stickers: https://joaotavora.github.io/sly/#Stickers https://joaotavora.github.io/sly/#Stickers LispWorks has a more graphical stepper / debugger so we might look into it. There might be sthg on the newer CLOG?
