package-shadowing-symbols

(package-shadowing-symbols package)

The shadowing symbols of package, in name order: the names its defpackage :shadow and :shadowing-import-from clauses declared, and the ones shadow and shadowing-import added at run time, each spelled as the symbol the package makes accessible under it. unintern takes a symbol out of the list. The designator is validated, so an unknown package signals like package-name.
