Try making each of those types an instance of Random, and using random
instead of next. Someone (the user or the Haskell implementor) still
has to manufacture the instances, but only once.

newStdGen :: IO StdGen
should do the trick. If you want a generator of a type other than
StdGen, you can always use a StdGen generator to seed it.
