p5-Safe-Hole

Make a hole to the original main compartment in the Safe compartment

We can call outside defined subroutines from the Safe compartment using share(), and call methods through the object that is copied into the Safe compartment using varglob(). However, these subroutines and methods are still executed in the Safe compartment, so they cannot call other subroutines that are dynamically qualified with the package name, such as class methods. Through Safe::Hole, we can execute outside defined subroutines in the original main compartment from the Safe compartment.
