[Haskell-beginners] Re: [Haskell-cafe] Just how unsafe is unsafe

Of course you could just put this random generator in the IO monad, but certain algorithms- like Monte Carlo - intuitively don't seem to operate in a IO monad to me.

For PRNGs, only State is needed, not IO. But you might find the `randoms' function useful: it returns in infinite list of pseudo-random values. --Max
