  ^^^^^^^^^
          "Obviously", indices are "always"
              1) unsigned non-negative integers,
              2) single-digit decimal numbers,
              3) powers of two, and
              4) literal values.
All four fit your example above. Some people consider one to be a
prime: for them, add
              5) prime.

          I'm not a compiler expert, but I can tell you that "obviously" is
a dangerous word.


Sincerely,
