On the Expressiveness of Purely Functional I/O Systems

It's possibly a very interesting paper, but all I can find online are citations and references--which means it might as well be printed in a 9 point font on the Moon for all the accessability it has.

It is also important to note that monads not special things wired into the compiler. They are built using normal Haskell code and live in the standard libraries.

That sounds promising. Care to show an example of how to read from stdin and write to stdout without using a IO Monad? Or just perform an question and answer session interactively without them/it?

It is quite possible to write real programs in Haskell without using any monads.

Again, care to post an example that can be compiled with GHC v6.4?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
