Re: Proposal: Move 'split' into a separate class in System.Random

I assume that there is more code that uses RandomGen in constraints than code that defines instances, thus the split of the split class might look like:

class StraightRandomGen g where  System.Random.next :: g -> (Int, g)  System.Random.genRange :: g -> (Int, Int)

class StraightRandomGen g => RandomGen g where  System.Random.split :: g -> (g, g)

All existing code that uses RandomGen in constraints would remain valid this way.

+1 ...although I don't like the name 'Straight'. =) -- Felipe.
