Readme

Often we need an efficient way to generate high quality pseudo-random numbers in Haskell. We have good generators themselves (for example, the mersenne-random-pure64 package), however, users are often tempted to store the generator in a lazy state monad. This causes performance problems.

This package provides an optimized Rand monad for monadic generation of random numbers from a state, with close attention to performance. You may have results an order of magnitude or more better than using Control.Monad.State to store your generator.
