(defpackage "FOO" (:case-sensitive t) (:use "CL"))
(in-package "FOO")

FOO[56]> (MAPCAR #'SYMBOL-NAME '(Help me find the car))

("Help" "me" "find" "the" "car")
FOO[57]> (MAPCAR #'SYMBOL-PACKAGE '(Help me find the car))

(#<PACKAGE FOO> #<PACKAGE FOO> #<PACKAGE FOO> #<PACKAGE FOO> #<PACKAGE FOO>)
FOO[58]> (MAPCAR #'SYMBOL-NAME '(Help me FIND the car))

("Help" "me" "FIND" "the" "car")
FOO[60]> (MAPCAR #'SYMBOL-PACKAGE '(Help me FIND the car))

(#<PACKAGE FOO> #<PACKAGE FOO> #<PACKAGE COMMON-LISP> #<PACKAGE FOO>
 #<PACKAGE FOO>)

you can also use cl:mapcar instead of MAPCAR.

I am not sure if wysiwyg matters.
CLISP uses case-sensitive package for FFI-based modules where
case-sensitivity of C has to map into CLISP.
see, e.g., clisp/modules/bindings/glibc/linux.lisp.

Those who don't know lisp are destined to reinvent it, poorly.
