private attribute don't function?

[Zhouxuan]

import std.stdio;

class A
{
        private int j = 1;
        
        private
        {
                int k = 2;
        }
        
private:
        int i = 0;
}

void main()
{
        A a = new A;
        writeln(a.i);
        writeln(a.j);
        writeln(a.k);
}

It compiles and output 0 1 2 repectively.
