Many early Common Lisp systems had impressive error handling. Certain exceptions would automatically break to an interactive Lisp window. But Common Lisp also has a fancy system for recovering from exceptions. So after you replaced the brok

Yes. I think MCL (aka Macintosh Common Lisp, an absolutely delightful environment from the 90s) and Allegro Common Lisp (the best Windows Lisp of that period) both called the REPL window "Listener".

You're completely right, of course. I'm pretty confident that I can parse untrusted binary data in Rust with nothing worse than a denial of service. (And I have over a billion 'cargo fuzz' iterations to prove it.) But WU
