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!

Fifth suppose to be Prolog, But in actuality its just a third/fourth generation trying to be "user-friendly" and "AI-generating".
Like LISP(a third generation language), FORTRAN(Same third generation) they all try to enforce one paradigm and view of how people should code. The next generation embraces multiparadigmality and DSL creation(C++/PureBASIC/Java).
Suffice to say all those High-abstraction languages which belong to third generation are useless in practice while practical, more free-form fourth generation stole their userbase.
Thats why LISP is less popular than say PureBasic. PureBasic is primitive and less abstracted, but its much faster and has all the practical tools/functions for quick program creation, it does not impede programmer productivity at all or enforce some academic purity or standard.
