No. That's expected. If you've overloaded a function from a base class,
only the functions in the derived class are in the overload set, so you
have to bring the base class' overload into the overload by either
overriding the base class overload in the derived class or by aliasing
it in the derived class. e.g.

module test;

public interface I
{
    void foo();
    void foo(int);
}

public abstract class A : I
{
    public void bar()
    {
        foo();
    }

    alias I.foo foo;
    public void foo(int i)
    {
    }
}

public class C : A
{
    alias A.foo foo;
    public void foo()
    {
    }

    public void bar2()
    {
        foo(1);
    }
}

I wonder whether a better diagnostic could help. But then again, maybe
the hiding would be intentional and the diagnostic would be
spurious/invalid. Not sure..
