        @bar = 123
      end

      def finalize
        puts "Before Destroying OBJECT: #{self.inspect}"
      end

    end


    f=Foo.new

    f.instance_variable_set(:@bar,rand)
    puts "Foo.bar is #{f.bar} now"

    f=nil # mark for sweep for GC

    # Force ruby to start the Garbage Collector
    # In a real program you don't have to do this
    # ruby will run the GC automatically.
    GC.start

    sleep 3 # make sure you will see the message
    # before ruby quits

    puts 'done'
