;;; COMMENT 4 on the book CL Recipes A Problem-Solution Approach by Edi Weitz
;;; chap.4-4 pag.95
;;; It's usually safer to use LET with *print-base*
;;; and in general with any variable of that kind :
;;; (let ((*print-base* 2)) (print 9))
;;; so things return to normal after the code
;;; completes (and also if it fails).
;;; However, *read-base* may not seem to work inside LET
;;; Think why... as that illustrates what read-time is.
