Both of these formats have advantages.  But it's easier to judge which is
better after actually using it, so I will defer any further decisions on
this for the moment, and commit the change as is.

BTW, I used the declarative debugger to debug my last few changes; this
has been very helpful in (amongst other things) evaluating the design.
At least one design change is in the pipeline as a result of this evaluation
process---more on this later.

Cheers,
Mark.
