The stream generator implements tha RandomGen interface.

This is really cool, though I think 'split' is a must. Maybe all instances could share the same stream in the background, then it wouldn't cause resource issues. Also, IMHO mkStream should produce an IO Stream (like getStdGen), as current implementation isn't referentially transparent; let the library user decide whether to use unsafePerformIO.

3) I have tested the package on Debian Linux Etch, using GHC 6.8.2.

Tested with Gentoo Linux on a 64-bit machine using GHC 6.10.1. On my system, it is less than 2 times slower than StdGen. -- Gökhan San
