Even earlier, I think, but there were and still are problems with

In 3.x, ASCII strings went away, but that was more of a removal.

Cobra seems interessant, open-source, but the dependance on Mono and

Otherwise, cobra have good ideas, a syntax similar to python.
One thing i really love is the "How-To" and the "Samples" pages on
