Cohen's "Ada as a Second Language" (ISBN 0070116075) goes into this in some
detail. I really didn't understand too well until I played with it myself
though. It is correct that class wide types have to be involved either as a
formal or actual parameter for dynamic dispatching to occur.

...unless there's some wrinkle I've missed.
