If all you want from IO is logging why not just use MonadWriter?
good question. my initial idea, being lazy, was that IO provides IORefs which might prove useful later on, but then i guess that a cleanly composed monad will behave better in the long term anyways. i have to add that this is my first large haskell project and i do many design decisions on a trial'n'error basis - naturally with a strong tendency to the error side. ;-) -- peter
