OK, it's at britseyeview.com/cumulative.txt.

I think enforcement of the call to super.handleCommand() would 
get most of the way down the road. More could be done if the 
compiler inserted the super call, and maintained an implicit 
class member equivalent to my 'cmdResult' that could be tested in 
override implementations of handleCommand(). But I think that is 
OTT.
