No, a pure function is one without any side effects.

There are no functions with side effects in Haskell, unless you use hacks like unsafePerformIO. Every Haskell function is perfectly referentially transparent, i.e. pure.

This is why we badly need a new term, say, io-pure. That means, neither has side effects, nor produces an action that when run by the runtime has side effects. Bob
