Hi Sage, This is pretty cool. With a non-OOP option on the table, I might finally get around to working on an IMGUI-like for Racket.
Have you thought about a reader extension to compress the notation? The `stateful-cell` function kinda acts like a box and kinda looks like a `syntax` (or `quote-syntax` w/ kw arg) form, both of which have special #-prefixed notations. Extending the reader to abbreviate `(stateful-cell 1)` and `(stateful-cell (λ _ (+ (x) (y))))` to, say, #?1 and #?(+ (x) (y)), respectively, could be a fun project.
