This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

A fast pseudorandom number generator, as presented by M.E. O'Neill on http://www.pcg-random.org, See that site for information on the particulars of the technique used. This particular implementation uses two Word64 of internal data and produces a Word32 of output per step. On 64-bit machines it's two to three times as fast as StdGen and uses the same amount of space.
