By the way, for future reference, I suggest adding a length count to the "Success!" output; I got confused for a bit when seeing C-M-x easily succeed up to very large depths (which is because it binds print-level to a small value). (let* ((print-circle t) (max-lisp-eval-depth most-positive-fixnum) (max-specpdl-size most-positive-fixnum) (deep-object (make-deep-object 6000)) (string (prin1-to-string deep-object)) (result (read string))) (when result (message "Success!
