Re: [Haskell-cafe] Lists and monads

2010/7/26 Kevin Jardine :

I suspect that things are not quite as difficult as they appear, however, but cannot find any tutorials on monadic list manipulation.

I'd suggest that you get as many pure values as possible from impure world, apply to them easy to use pure functions (list processing, etc) to get the desired result and, only then, put result back into impure world. It is even more exciting because you can create and combine impure actions as pure values.
