I have a use-case where I want to test a program for some gambling game. The random numbers I need should be in a very small area (1 to 9), and there\'s no realquality neede
The mersenne-random-pure64 package is very fast, as is mwc-random.
I found out about the Xorshift random gen, which perfectly suits my needs. I'm going to implement it in Haskell and put the implementation online.
It's done: Xorshift is uploaded to hackage, and needs some improvement by me.
