Perhaps our experience is different. I have seen relatively few instances
of such a relationship (nor have I myself had much reason to do write
anything like that). But when I have seen them, they were completely
unnecessary (confusing, in fact), and clearly indicated that the
abstractions needed to be combined into a single package.
I'm talking about just a pair of abstract data types that are intimately
related. But I sense that you and the other posters are talking about
large packages (say, a subprogram library such as binding).
