Following code doesn't work(it's not the actual code but it represents it). Is there some rule about function overrides that I don't know about?

class a {
public override string toString() {
//...
}
}

class b : a {
public override string toString() {
//...
}
}

The error I keep getting no matter what says: Error: Multiple Overrides of Same Function. Anybody know what I should do?

Okay. Realized this wasn't actually affecting my program, but is there any explanation for why this doesn't work?

It works for me.

The "shorten" link on run.dlang.io no longer works, but here is a working example:

```
import std;

class A {
    public override string toString() {
        return "a";
    }
}

class B : A {
    public override string toString() {
	    return "b";
    }
}

void main()
{
    A a = new A();
    B b = new B();
    writeln(a);
    writeln(b);
}
```

I think he is referring to this:

import std;

class B{
    public override string toString(){
        return null;
    }

    public override string toString(){
        return toString(null);
    }
}

void main() {
    B b = new P();
}

Error: function `B.toString` multiple overrides of same function

I mean he may be having a duplicate method in the same class.
