I think your real point is that some things we still haven't figured out how to express functionally. Right?
That's my point, at least. Currently, AFAIK, the only way to get input and produce output is via the IO monad, so it is de facto necessary for all 'real' programmes, it need not remain so (though I cannot imagine how to functionally express 'readFile "Data.txt" >>= print . performAwfullyCoolFunctionalStuff' - surprise me :). Read "IO is important" as a description of current affairs, not as a claim of the inherent grandeur of it. Cheers, Daniel
I would certainly agree with that part. Perhaps you exaggerating when you wrote "IO is important because you can't write any real program without using it."
