As a shameless plug, have you tried "Tackling the awkward squad?". Indeed I/O in Haskell doesn't suck.

Well I thought I had a good grasp of Haskell I/O, but I read that paper anyway and found many interesting things (exceptions and Concurrent Haskell are both new to me, and the FFI is something I've only touched on briefly). I'd recommend that to others struggling with the IO monad; I wish I'd read it three years ago! Thanks
