this is simpler testcase:
-----------------------------------------------------
version( D_Version2 ){
    mixin("extern(C) void printf(const(char)*, ... ) ;");
}else{
    extern(C) void printf(char*, ... );
}


class MyTest {
    void delegate(int)[]    list ;

    public void run(){
        test3(this);
        test2(this);
        test1(this);
        foreach( dg; list) {
            dg(3);
        }
    }

    static void test1(string name = "test1\0" )(MyTest obj){
        printf("out: `%s` = `%x` \n\0".ptr ,  name.ptr, cast(void*) obj );
        void     add(int i){
            printf("in: `%s` = `%x` \n\0".ptr ,  name.ptr, cast(void*) obj );
        }
            obj.list    ~= &add;
    }

    void test2(MyTest obj){
        test1!("test2\0")(obj);
    }

    void test3(ref MyTest obj){
        test1!("test3\0")(obj);
    }
}

void main(){
    auto t    = new MyTest;
    t.run;
}
