      It's unfortunate that the learning curve to get to monads is really, really steep. But when you're there, it's just nice. Recommended reading and recommended blog: https://bartoszmilewski.com/2014/10/28/category-theory-for-programmers-the-preface/ … by @BartoszMilewski :)

      This. Haskell is hard because programming is hard. Primitives in Haskell as a side effect (pun) also teach concepts like managing state, which usually takes years to develop. Path of least resistance in Haskell is managed state. Path of least resistance in Imp. is global state.

      Just like most bad things in CS, this line of thinking starts with an idea that is true, but then extrapolates it waaaaay beyond the place where it is beneficial into a realm of total lose.

      But, manipulating global state is how your computer actually works. Pretending that that is inherently bad will only lead you to a sad place. At the same time, yes, unnecessary global state makes things confusing. But the right amount of global state is a good idea.

      Replying to @Jonathan_Blow @fabricatedmath and

      Pretending that you can magically solve your problem, without the right amount of global state manipulation, is basically the same thing as obfuscation.
