Your "old.h/cpp" examples don't use namespaces at all. `old` is a
class, not a namespace.

Also, your new wording answers very few of the questions I posed. It's
the same terrible wording, but with "functions" changed to "names" and
a statement about where this grammar can go.

Just your example raises many questions. For example, what namespace
is `foo` in? How do you access them if they're not in the namespace?
If non-exported names aren't in that namespace, can you define two
entities, one exported and one not, with the same name and have that
just work because of the implicit namespace business?

And you never deal with the question of multiple translation units,
which is at present a complete non-starter.
