Consider this code:

module bar;

extern(C) func();

module prog;

import foo;
import bar;

void main()
{
    func(); // error
    foo.func(); // ok
    bar.func(); // ok, uses C binding (no name mangling)
}

In this case, even though the C function is not mangled or in any other
namespace, the module can be used for unambiguous calling.

Right.

module foo;

void func() {}

module bar;

extern(C++, foo) void func(); // foo::func in C++ land

module prog;

import foo;
import bar;

void main()
{
    func(); // error
    foo.func(); // ALSO error

No, not an error. Why would it be?

I believe Steven expects things to work this way:

module bar;

extern(C++, foo) void func();


module prog;

import bar;

void main()
{
   foo.func(); // Calls bar.func (or is that bar.foo.func?)
}
