OK, it's at britseyeview.com/cumulative.txt.
However, I now realize you can do better in D. The base class
needs to define an array of delegates. It appends its handler to
the array, then derived classes each append their handler. The
append is done like:
handlers ~= &Red.handleCommand;
Am I right in thinking that this makes the calls non-virtual?
Anyway, the result is I think exactly what I wanted.
The example is at britseyeview.com/cum2.txt.
