+C<Symbol::delete_package> is a bit too powerful. It undefines every symbol that
+lives in the specified package. Since perl, for performance reasons, does not
+perform a symbol table lookup each time a function is called or a global
+variable is accessed, some code that has already been loaded and that makes use
+of symbols in package C<Foo> may stop working after you delete C<Foo>, even if
+you reload the C<Foo> module afterwards.
