TITLE: do namespaces need protected/private

(Newsgroups: comp.std.c++)


PROBLEM: <biderd@abm.si>

Namespaces have one deficiency: their members cannot be
protected from the outside like class members can be with
a "private:" or "protected:" keyword.

But you don't need those. First, namespaces can't be derived from
each other, so I can't see much use for the protected keyword.
Secondly, you can use unnamed namespaces to implement private members
as follows:

namespace A
{
  namespace {
    int x,y,z; // only functions in A can access these!
  };
};
