The point is to give the signal handler access to an object. If you simply point the signal handler to a subroutine, you do not have a way of accessing $self, unless it is stored in a class variable. By defining the signal handler with a closure, you can call the signal handler as if it were a method instead of a regular subroutine, therefore giving it access to $self (and the ability to access its methods and data).
