Martin's "random" wishlist: - I wish the cool convenience methods in TLR like nextInt(least, bound) could be promoted to Random.java, or perhaps to a utility class Randoms.java - I wish that TLR didn't continue to extend the life of Random's poor PRNG, and at least provide one with a 2**64 period. I don't see much value producing a sequence compatible with Random, given that setSeed is not available. but it's probably too late.
