That would explain why a[0] and *a are different notations for the same
thing, and a[2], *(a+2), and 2[a] are also different notations for the
same thing. a[2] is defined as a shortcut for *(a+2), which is why 2[a]
works. The "array" notation in C is a different notation for address
arithmetic. I stand by my statement.

Meanwhile, in Ada, A (0) and A (2) are legal, but A.all, 2 (A), and (A +
2).all give compiler errors.

You've got that right.
