I rely on Math::TrulyRandom when I need better than built in rand

    I agree with Math::TrulyRandom, but since the generation might take a long time, it is best to use this only as a seed generator, and use rand which is pretty reliable.

      use this only as a seed generator, and use rand

      The random seed set by srand is usually 32 bits. If you put 32 bits of randomness in, you cannot expect more than 32 bits of randomness out. Someone might be able to predict the rest of the sequence. That might be good enough, and it might not.
