LLM hooked into a Lisp REPL adds functions on demand that persist across restarts

A demo shared by GeoffreyHuntley hooks an LLM loop into a Lisp REPL: the model adds functions to the REPL as needed while the app runs, and those functions persist across restarts. Instead of the usual readfile + editfile + bash compile loop, functionality is extended via prompt at runtime — effectively letting the application grow capabilities while running.
