There's no way to do this. Perl is a dynamic language, and functions are added to packages at runtime all the time. Consider that subclassing happens on-the-fly with @ISA (rarely put inside a BEGIN block), and that AUTOLOAD means a package (or a class's ancestor) might decide to handle -- or decline -- some call, pretty much arbitrarily.
