Hello Stanislav,

It wasn't designed to have multiple namespaces at all to begin with. But as
now have them we should at least think of what we want...

How so?

namespace foo {
  namespace bar {
    class baz {}
  }
}

According to your won words it is all about name substitution. Explicitly
you were talking about simple text replacement. Now that in mind I see and
easy replacement here. That is 'bar' becomes 'foo::bar' and 'baz' obviously
becomes 'foo::bar::baz' or can you find something else?

Actually we already have this:

namespace foo;
namespace foo::bar;
class baz {}

And that does exactly what I described above. But maybe I just to stupid
:-)

Best regards,
 Marcus
