Trying an example from TDPL (p. 214) results in linker error.

Source:

import std.stdio;

interface Transmogrifier
{
    final void thereAndBack()
    {
        transmogrify();
        untransmogrify();
    }

private:
    void transmogrify();
    void untransmogrify();
}

class CardBoardBox : Transmogrifier
{
    override private void transmogrify()
    {
        writeln("transmogrify");
    }

    override private void untransmogrify()
    {
        writeln("untransmogrify");
    }
}

void main()
{
    (new CardBoardBox).thereAndBack();
}


Linker output:
OPTLINK (R) for Win32  Release 8.00.2

The same issue occurs, when private is replaced with package.
protected and public do work.
