Re: Pike 8.0 beta

FWIW, in Matlab "rand" always generates a pseudo-random-sequence using the
same random numbers. After a Matlab restart the output of rand is exactly
the same. I often rely on it to return the same numbers when the a script
is executed twice. (Using rng('default') the sequence can also be restarted
from the beginning during script execution).

As such I would also like for pike to have a simillar pseudo random number
generator, where random_seed() (or any other name) should always return the
same sequence at either 1. fresh start of pike 2. given a specific seed.
