This is good to know; it just made part of the project even simpler. I was
prepared to write the project assuming the behavior in my question, but it
would have been more complicated.

Good to know. Leads to a new question: Suppose I have included foo.e as
bar and as baz. Is it possible to write a procedure that overrides one of
the publics in one of the namespaces? IOW, can I define namespaces other
than by includes? If this is answered in the docs, tell me so - I haven't
had the chance to read them thoroughly, only glanced through them.
