Hi Doug:

What is our current view of:

traversal allSalaries(CondTravVisitor,CountingVisitor, SummingVisitor c)

The idea was that the CondTravVisitor controls the CountingVisitor and
SummingVisitor. But this does not seem to work.

In terms of plug-and-play visitors, we would have
a CondTravVisitor which calls a bunch of other visitors, here only 2:
CountingVisitor and SummingVisitor. The CondTravVisitor is
not interested in any results from the Counting and SummingVisitors.
Only at the end we want to get the values in those two visitors.

While we don't have plug-and-play visitors in Demeter/Java, there should be
a way to simulate them. What is the best way?

Doug and Binoy:

Why do I get a failure in:

/proj/adaptive/www/sources/DemeterJava/examples/j-c-holding-around

Would like my students to use around methods.
