Comment:
The new attachment (SplittableGenClass.patch - sorry, should have replaced
the old) seems to be the consensus on the ML. It implements:
{{{
class RandomGen g where
next :: g -> (Int, g)
genRange :: g -> (Int,Int)
genRange _ = (minBound, maxBound)
class (RandomGen g) => SplittableGen g where
split :: g -> (g, g)
}}}
