Comment by tome

Yes, absolutely, I would say for almost every programmer, certainly for me. "Scrap your iteration combinators" goes into more detail. foldl' is a bit too simple to replace with for_, but for almost every other use case, yes, I do use for_. In fact, I find it remarkably liberating compared to the "iteration combinator" conventional wisdom that has been passed down from Haskeller to Haskeller over the years.

I don't feel that monads are particularly complicated. I have several non-Haskellers programming in Haskell at work, using monads. They just think they're writing a sequence of statements. I feel that mixing monads is complicated, which is why I recommend an IO-wrapper effect system (Bluefin or effectful), so that you don't need to mix.
