 (export (intern "SHOES" (make-package 'temp)) 'temp)   T
 (find-symbol "SHOES")   NIL, NIL
 (use-package 'temp)   T
 (find-symbol "SHOES")   SHOES, :INHERITED
 (find (find-package 'temp) (package-use-list 'common-lisp-user))  #<PACKAGE "TEMP">
 (unuse-package 'temp)   T
 (find-symbol "SHOES")   NIL, NIL
