I have no flipping clue what "system-level programming" means these days, and I'm hoping someone could spell it out. I used to think (back when I was doing that sort of stuff) that it mean operating systems level stuff- device drivers, embedded, real time, stuff like that. But no language with a GC or non-trivial run time is a good fit for that. From usage, I now think it means "we refuse to use Java".
