Hi,

Google and Go could be interesting.
http://scienceblogs.com/goodmath/2009/11/googles_new_language_go.php

Comment 26.
"You know, all this hoopla over "Go" and how wonderful it is and yadda
yadda yadda was being pushed by the ETH Oberon group and all Oberon
users back in the late 90s. With few exceptions, certainly none large
enough to fundamentally change the language for, Go does _NOTHING_
different than Oberon-2.

Why can't people just use Oberon and move on with life? I'll tell you
why -- because it was designed by Niklaus Wirth. People HATE Wirth.
He's the anti-Christ..."

Comment 41.
"4. The Guy who wrote Unix and C is working on it. He's got something
of a track record. If he re implements the Unix Kernel in GO and
Google open sources it... then anything is possible."

I have no comments, everybody could guess on this list..

Regards,
Jozsef
