    9  * This patch deprecates `is_perfect_power`.
    10  * It implements a new function, `perfect_power`, wrapping Pari's `ispower` function, expressing an integer in the form a^b^ with `b` maximal.  This revealed a bug in Pari for negative even powers: I'm in the process of reporting it.
    11  * It adds cross references between `is_power`, `is_power_of`, `is_prime_power` and `perfect_power`.
