I buy Doru's examples approach. Usually interesting objects are used in some kind of context and there may be a flow that the above illustrates, instantiation => initialization => use. All this is possible with examples, and examples have a pragma to identify them to tools. So I would push the examples direction. I guess the kernel of this approach is to create a method that creates and uses some object, and that is labelled with a specific pragma identifying it as an example. It can then serve as both a test and an example to users. > cheers -ben > _,,,^..^,,,_ best, Eliot
