symbols—a designator for a list of symbols.
package —a package designator. The default is the current package.
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.
(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)
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.
Current state of the package system.
