It would not work here. Variates cannot be global variables
as they have private state:
0) - Their base random number generator (eg Parks as per
ObxRandom & Bugs, or Lagged Fibonnacci as per Knuth, or
user defined, maybe 'Chaotic' as per Tkachov et al!)
2) - Their defining parameters (eg mean, standard deviation,
Kertosis)
3) - Their state vector. This must be private to allow reruns,
and so that different callers don't interfere which each other.
Such interference could even alter the perceived distribution.
