Hi Doug:

please can you help to create a list of DAJ related projects for
COM 3360:

1. Visitors. From cd generate:
   CheckingVisitor (for checking whether object conforms to cd)
   PrintingVisitor, etc. as in DemeterJ

2. Multiple visitors per traversal (as in DemeterJ)

3. Have a TraversalThisJoinPoint and expose objects visited
   during traversal (as in version of DJ by Pengcheng Wu).

4. Edge join points.

etc.
