• unexport symbols &optional package → t

• symbols - a designator for a list of symbols.
• package - a package designator. The default is the current package.

unexport reverts external symbols in package to internal status; it undoes the effect of export.

unexport works only on symbols present in package, switching them back to internal status. If unexport is given a symbol that is already accessible as an internal symbol in package, it does nothing.

(in-package "COMMON-LISP-USER") → #<PACKAGE "COMMON-LISP-USER"> 
(export (intern "CONTRABAND" (make-package 'temp)) 'temp) → T
(find-symbol "CONTRABAND") → NIL, NIL
(use-package 'temp) → T
(find-symbol "CONTRABAND") → CONTRABAND, :INHERITED 
(unexport 'contraband 'temp) → T
(find-symbol "CONTRABAND") → NIL, NIL

Current state of the package system.

If unexport is given a symbol not accessible in package at all, an error of type package-error is signaled.

The consequences are undefined if package is the keyword package or the common-lisp package.
