> The recommended way of writing a program in most languages demands some level of understanding what you're writing Sure, some. I think this discussion is about exactly what and how much, when it comes to Haskell. > the recommended way of doing that is to understand Monad. That doesn't ring true to me, not from how I learned Haskell and not by analogy with how I learned other languages. I don't remember having to "understand Monad" to write in "do" notation. Quite the opposite in fact. I vividly remember trying to "understand Monad" and being unable to, and then just giving up and trying to use do notation, finding it easy, completely unhelped by what I was trying to "understand", and regretting having spent all the time "understanding". But it's been a long time since I learned a language so maybe I'm mistaken. I would appreciate the point of view of others who have fresher eyes. I will concede that people have a harder time learning Haskell than Python (although I don't think anyone understands the exact reasons) but you gave a very specific example of a program that is supposedly requires some deep understanding to write in Haskell. I wanted to give a counterpoint so people can decide for themselves. That's as far as my claim goes.
