I have been trying to understand closures in haskell and how they relate to side effects. I have been looking around but all I find are trivial examples with no side effects. Please let me know if you know of any examples.
what you mean by 'closure'? in Haskell, expression may have a side effect only if it has "IO a" return type. it is then whole point of pure lazy language - evaluation of pure (not "IO") expression can be deferred until it's value really need and language guarantee that this don't change anything (including lack of any side effects) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
