Really? I would have thought this is a job for the ST monad, in which case the API can be wrapped up in a runST or similar; no need for leaking IO monads.
Or am I missing something? Regards, Martin My music: http://www.youtube.com/user/thetonegrove (please visit!) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
