This is a good proposal.

In VW NC Vs. 3.0 the exception HaltInterrupt is subclassed to
GenericException and ControlInterrupt. Both

 [self halt: 'a halt'] on: HaltInterrupt do: [:exc | Transcript show: 
exc class name; cr].


and



 [self halt: 'a halt'] on: GenericException do: [:exc | Transcript show: 
exc class name; cr].


write the class name of the exception into the transcript. 
My statement that  the Halt exception is not handled by a
more general exception does not hold for VW.
