Re: [Haskell] randomgen for foreign random functions

There's a standard approach, originally due to Lennart Augustsson.

Have a single function that generates an infinite supply mkSupply :: IO Supply

Note that Simon's code is essentially isomorphic to the splittable supply library referenced in my last message---but the library gives a few more knobs you can turn. Simon, you left out the declaration for "MkSplitUniqSupply"! -Jan
