Re: [Haskell-cafe] STM and random numbers

Wow, lots of great ideas. Thanks, guys. Lemmih, I worry about the uncertainty in the semantics that seems to be introduced by the unsafe stuff. But I actually hadn't noticed GHC.Conc.unsafeIOToSTM before, so it's good to know it's there. Rich, Even if I use randomIO outside the STM code, I don't know of a (safe) way to bring it in. Anyway, the number of random values needed depends on other stuff going on within the STM part. Christian, I think setStdGen has the same problem as just using randomIO and ignoring the initial seed - there's no nice way of moving the (IO a) value generated into the STM monad. Rob, Henning, I think I'll take this approach, or something similar. Thanks for the pointers. -Chad
