;;; BUG: The compiler will macroexpand the forms below (char str N)
;;; will expand to internal SBCL code instead of our (setf char). It
;;; is because macrodefinitions during bootstrapping are not included
;;; in the host's environment. It should, but we have to think how to
;;; avoid conflicts (package renaming??)
