I'm still not certain about the exact semantics of using declarations.
It seems to me that
namespace A{
void f();
}
using A::f;
namespace A{
void f(int);
}
using A::f;
void g(){
f(4);
}
should be illegal. The redeclaration of 'using A::f;' is certainly
correct, however, the selected set of declarations should be the one
found at the first declaration.
If A::f(int) is visible inside ::g, please let me know why.
TIA,
Martin

In my interpretation, a using declaration brings the current
definition of the specified name into the current namespace,
therefore, the redeclaration would bring the declarations of both
A::f(char) and A::f(int) into the global namespace.
But you're right, this is not explicitly stated in (my non-final copy
of) the Standard. Time for one more question in comp.std.c++
