What an eerie feeling reading this, or was it prescient?:

"""

    def fizz_buzz_encode(i):
        if   i % 15 == 0: return np.array([0, 0, 0, 1])
        elif i % 5  == 0: return np.array([0, 0, 1, 0])
        elif i % 3  == 0: return np.array([0, 1, 0, 0])
        else:             return np.array([1, 0, 0, 0])

me: That's enough setup, you're exactly right. [<--- !!] [...]
