Spricht etwas dagegen, einen namespace zu verwenden, der gleichzeitig
ach eine Klasse ist? Das sähe etwa wie folgt aus:
class Foo {
};
namespace Foo {
};

Ja, § 7.3.2/4 "A namespace-name or namespace-alias shall not be declared
as the name of any other entity in the same declarative region. A
namespace-name defined at global scope shall not be declared as the
name of any other entity in any global scope of the program. No diagnostic
is required for a violation of this rule by declarations in different
translation units."
Was sollte auch bei
#include <iostream>
#include <ostream>
namespace Foo
{
void bar() { std::cout << "Hello from namespacen"; }
}
class Foo
{
public:
static void bar() { std::cout << "Hello from classn"; }
};
int main() { Foo::bar(); return 0; }
gscheit's rauskommen?

Falk

Das einzigste was mir einfallen würde ist, dass man eine Klasse gleichen |
Namens im Namensraum macht:
namespace foo
{
class foo
{
..
..
};
}
Dann weiß man zumindest eine der Klassen die drin versteckt ist..
