How will the variable `outer` become the reference to the 
current `X` object (if that makes sense?). Does the compiler 
do it automatically?

I think you'll need to do this:

class X {
    private int num;

    struct Y {
        X outer;
        int fun() { return outer.num; }
    }

    Y y;
    this(){
        y = Y(this);
    }
}

void main(){
    import std.stdio : writeln;
    auto x = new X();
    x.num = 10;
    writeln(x.num);
    writeln(x.y.fun());
}

Prints:

10
10

ah, that's annoying, but I guess it's the only solution as it 
stands.
