Yes, that would be true. But the kinds of groupings that we're talking
about are supersets of namespaces, not semantically equivalent to
them. To use Eric's "shoe" analogy from earlier, it's like insisting
that we use the term "sneaker" to refer to all footware, including ski
boots and birkenstocks ...
