What I would like to know is why it is impossible to _extend_
a namespace using its alias...
------------------------------ somewhere
namespace A { namespace B {
...
}}
namespace A_B = A::B;
----------------------------- somewhere else
#include <somewhere>
namespace A_B { // not allowed, must be original-namespace-name
...
}
-------------------------------------------
?
It can't be for protection against wild name replacements because
it could be done with macros, anyway. So, why is it?

Hello,
why is it not possible to declare a namespace (either expanding it, or from
scratch) like:
namespace A::B
{
// ....
}
This should be exactly equivalent to:
namespace A { namespace B {
// ...
}}
but less verbose, while it's still very intuitive.
