Hello haskell-cafe,
just another interesting discussion in russian forum raised such idea:
we all say that monads are the haskell way to do i/o. is it true? may
be, uniqueness types, just like in Clean and Mercury, are real way, and
monads are only the way to write programs that use uniqueness
Very rarely is a nontrivial solution the only way. Monads are a
construct that nicely represents the sequencing side-effecting
computations in a pure and strongly-typed environment. They are a nice
way to do it, but certainly not the only one.
Now I'm not confident enough to boldly make this
Gah. For the first time ever, I seem to have accidentally done a reply to
sender. (IE Bulat please ignore this message)

hmm, my inexperienced forwarding attempt mangled the message...

Hbc implements the IO type by request/response IO. I.e., the original
Haskell I/O system. People who assume IO involves some RealWorld being
passed around are just making unwarranted assumptions. The Haskell
definition leaves the IO type abstract.
