Yes, there is pow(real, int) in phobos that calls row(real, real) if the exponent is negative. Somehow the overload resolution error I got when calling pow with (double, int) made me think there is no such an overload. Anyway, though the proposed implementation may be faster for negative exponents, it doesn't work for int.min and so needs more thought.
