- Look at all the "quite experienced" C programmers who don't know that
- a[i] = i++;
- is not allowed.
You're kidding, right? I was sure it wasn't _recommended_, but I
didn't know it was explicitly forbidden.
According to the rules of ordinal evaluation:
 binds first, left to right, so we have a[i].
++ binds next, right to left, so i is now i+1.
= binds last, right to left, so a[i] has the value i+1.
Of course, when compiled, the ++ gets eval'd *AFTER* the assignment
(StunOS 4.x standard compiler AND gcc do this -- is this right?).

I don't know a compiler that would reject the code. Of course, that
speaks loudly for the state of education among compiler writers, I
