Any reason not to mimic the Random interface?  I.e. provide both
     randomN :: StdGen -> Double
and  randomNs :: StdGen -> [Double]

BTW, can it be made more general, and parametrise the distribution
function?

Contrary to (all?) others, I think the *sigma+mu pattern is so
ingrained into everybody wanting this, that the standard normal
approach is sufficient.
