Hmmmm. I take back part of my earlier comment, as this looks weird. I think it
should be like this:

namespace x {

namespace foo {

namespace bar {
class Baz;
struct Qux;
}

}  // namespace foo

}  // namespace x

If the inner namespace is homogeneous (i.e., you can run it all together without
vertical whitespace), then the opening/closing braces can also be run together,
and because of that you don't need the closing comment on the closing brace.

Done.

You probably want to put this as close as possible to the *start* of this
namespace (i.e., up top), rather than at the end.

Done.
