Sixth Generation Programming Languages

So earlier this year we were doing a class intro and my professor mentioned something about a 6th generation programming language?

Are there any such projects yet or was my prof just throwing it out there?

Also semi-related. You know the new language D? What does it qualify as?

Please don't return me to Google. It doesn't return any relevant results.

Thanks!
