Re: [Haskell-beginners] IO and purity

Thanks for removing a misconception about everything being a function. My original example used writeFile, which is why I used the term 'function'. Refactoring text is more difficult as compared to haskell code :) On 26 April 2015 at 17:34, Kim-Ee Yeoh wrote:

I am myself an absolute beginner in Haskell and Functional Thinking so I hope to get some constructive feedback on my mental image of this situation.

When you write: "From the perspective of the programm, you just call a function without argument that returns a string"

you veer close to the lousy thinking that Everything is a Function. Conal Elliott did the delousing here:

Have a read, and if you're not convinced, come back here and ask for more help.
