           Summary: Protected class members in different file inaccessible

Example:

a.d:
class A
{
protected:
    void f()
    {
    }
}


main.d:
import a;

class B: A
{
public:
    void g(A a) // using g(B b) it works
    {
        a.f(); // error
    }
}

int main()
{
    auto b = new B;
    b.g(b);
}


dmd main.d a.d

Error: class a.A member f is not accessible


This is ONLY if A is in a different file (else B can access any of A its members due to module accessibility). If g accepts B instead of A it works though.

I think this is a major bug.

It also works with the following calls: f(), this.f() and super.f()

This is exactly the way it is designed to work. Accessibility is determined by the 'this' pointer, not the function it is in (C++ operates the same way). And, of course, code in a module has all access to other classes in the same module.

Perhaps, but it could be a future enhancement. I'm not sure about the pros vs cons, maybe encapsulation would break under this enhancement. The damage seems limited though.
