C++ pow() is a function of doubles, not ints. You can't define it in terms of std::accumulate.

  The integers are a subset of the reals, so the rule still should hold.

    But that's exactly the issue. Pick one subset, and it's 0. Pick a different subset, and it's 1. There is no rule which always makes sense.

      Why not just agree that pow(a, b) is discontinuous at a = 0.0?
