rng-utils

This simple utility wraps an IORef around random for the common use case of initializing an RNG once and using it in various places within an IO context. The haddocks should otherwise be self explanatory.

Any comments, improvement opportunities, feedback most welcome.

Upgrade Notes

In version 0.3.0, rng-utils switched from targeting mwc-random to random. random sees more use in the Haskell ecosystem, has fewer dependencies and the performance difference was negligible in comparison to the concurrency mechanism. If you feel strongly that mwc-random should be part of the library, let us know in an issue and we can look into supporting multiple backends.
