Indeed. But it builds on C.

So I'd need to understand more to believe that claim. And for the record,
what I'm going for is a new C that is still C enough to be useful but
fixes the problems enough to be a new language. Someone asked about
C++ and D, nope. Too far from C. I just want a C that fixes enough
of the problems that it is more acceptable to modern programmers but
is still C. Not sure if I'm explaining that well enough.
