Function PACKAGE-SHADOWING-SYMBOLS

Syntax:

package-shadowing-symbols package => symbols

Arguments and Values:

package---a package designator.

symbols---a list of symbols.

Description:

Returns a list of symbols that have been declared as shadowing symbols in package by shadow or shadowing-import (or the equivalent defpackage options). All symbols on this list are present in package.

Examples:

     (package-shadowing-symbols (make-package 'temp)) =>  ()
     (shadow 'cdr 'temp) =>  T
     (package-shadowing-symbols 'temp) =>  (TEMP::CDR)
     (intern "PILL" 'temp) =>  TEMP::PILL, NIL
     (shadowing-import 'pill 'temp) =>  T
     (package-shadowing-symbols 'temp) =>  (PILL TEMP::CDR)

Side Effects: None.

Affected By: None.

Exceptional Situations:

Should signal an error of type type-error if package is not a package designator.

shadow, shadowing-import

Notes:

Whether the list of symbols is fresh is implementation-dependent.
