random:
    description:
        random[mu, sigma] input-seq
        multiply the coeffs in input-seq by a random number from a normal distribution
        where mean = mu, and standard-deviation = sigma

    examples:
        random[1, 0.7] range(|1>, |5>)
            1.352593|1> + 2.120979|2> + 2.134905|3> - 0.163504|4> + 1.371605|5>
