Re: [Haskell-beginners] Haskell for Imperative Programmers

An intuition that really clicked for me is that in Haskell IO code, as in all Haskell code, you are describing a pristine and perfectly inert data structure. It happens to *represent* a set of imperative instructions that the totally impure runtime environment can execute, but that's not your problem! On Tue, Jul 10, 2018, 4:55 AM Olivier Revollat wrote:

May be something like this?

Hi, I've been using imperative languages for 20 years now :)

I'm a beginner in haskell and I love the paradigm shift you feel when you come from imperative programming. I found interesting articles like : https://wiki.haskell.org/Haskell_IO_for_Imperative_Programmers

Do you have any other ressources like that ? I'm not looking for how to use haskell in imperative style (e.g. with "do" notation, ...) no no ! I'm looking articles who explain how NOT TO USE imperative style with haskell, and help thinking the paradigm shift ...

Thanks :)
