[PD] Random

[Dan Wilcox]

Ok, makes sense. A [date] object would still be useful for my case: generating filenames with timestamps. :)

That's why I was thinking of some sort of [seed] or [salt] object which would wrap reading from a default pseudo-random source such as /dev/random or some system equivalent.
