In most any (writable) buffer, you can type: (prog1 (terpri) (pp (function-returning-hairy-stuff))) C-u C-x C-e This won't work only in buffer where C-x C-e is not bound to eval-last-sexp. In those buffers you can type C-u M-x eval-last-sexp RET instead of C-u C-x C-e You can also use ielm: M-x ielm RET (pp (function-returning-hairy-stuff)) RET (pp (other-function-returning-hairy-stuff)) RET ;; etc… -- __Pascal Bourguignon__ http://www.informatimago.com/ “The factory of the future will have only two employees, a man and a dog.
