#### 11.2.10 shadowing-import [Function]

`shadowing-import` symbols &optional package ⇒ t

#### Arguments and Values::

symbols—a designator for a list of symbols.

package —a package designator.

The default is the current package.

#### Description::

shadowing-import is like import, but it does not signal an error even if the importation of a symbol would shadow some symbol already accessible in package.

shadowing-import inserts each of symbols into package as an internal symbol, regardless of whether another symbol of the same name is shadowed by this action. If a different symbol of the same name is already present in package, that symbol is first uninterned from package. The new symbol is added to package’s shadowing-symbols list.

shadowing-import does name-conflict checking to the extent that it checks whether a distinct existing symbol with the same name is accessible; if so, it is shadowed by the new symbol, which implies that it must be uninterned if it was present in package.

#### Examples::

     (in-package "COMMON-LISP-USER") ⇒  #<PACKAGE "COMMON-LISP-USER">
     (setq sym (intern "CONFLICT")) ⇒  CONFLICT
     (intern "CONFLICT" (make-package 'temp)) ⇒  TEMP::CONFLICT, NIL
     (package-shadowing-symbols 'temp) ⇒  NIL
     (shadowing-import sym 'temp) ⇒  T
     (package-shadowing-symbols 'temp) ⇒  (CONFLICT)

#### Side Effects::

shadowing-import changes the state of the package system in such a way that the consistency rules do not hold across the change.

package’s shadowing-symbols list is modified.

#### Affected By::

Current state of the package system.
