[Haskell-cafe] Replacing IO with pure values

[Paul Brauner]

There's https://hackage.haskell.org/package/IOSpec which provides a pure
implementation of the IO monad. Once you're done testing your code you can
import Test.IOSpec.Surrogate which declares type IOSpec f a = IO a.

Would be a nice use case for ML-style modules btw :)
