Is there any way that an overriding method in an object sub-type can
call the overriden method in the supertype ?
I am thinking of the kind of thing done by using the 'super' keyword
in java, where it is possible to define a method in a super class to
provide certain base functionality, then override that method in a sub-class with a method that calls the super class method to perform the
base functionality, then adds extra functinoality at the subclass level.
Any ideas anyone ?
