Override with function overloads

[jmh530 via Digitalmars-d-learn]

In the code below, the second to the last line fails to compile. 
As far as I can tell it is because the override also overrides 
all overloads. I could imagine why it would occur with a virtual 
member function, but I would think it wouldn't be necessary with 
a final one.

@system
unittest
{
    class Foo
    {
        final string bar(double d) { return ""; }
        void bar(int x) { x++; };
    }
    class Foo2 : Foo
    {
        override void bar(int x) { }
    }

    Foo2 foo2 = new Foo2;
    foo2.bar(1);
    string x = foo2.bar(1.0); //error that bar is not callable 
with doubles
    //string x = foo2.Foo.bar(1.0); //this compiles
}
