This indeed another useful technique. However, there are some small gotchas.
You can usually use singleton objects, but in many cases you will need
access values so you have to make them "aliased."

By the way, several of these techniques are described in detail in my paper
"Building Frameworks in Ada95", proceedings Ada-Belgium'99 Seminar, Leuven,
1999.
