    # Squeeze is kind of like the opposite of absorb; it copies trits
    # from internal state to the ``trits`` parameter, one hash at a
    # time, and transforming internal state in between hashes.
    #
    # However, only the first hash of the state is "public", so we
    # can simplify the implementation somewhat.
    #

    # Ensure that ``trits`` can hold at least one hash worth of trits.
