If you never want to learn Haskell (or PureScript or similar) then the author even says in the `If They're So Wonderful Why Aren't They In My Favorite Language?` section: "If you don't need IO sequencing, or purity because your language doesn't care about purity, or the list implementation's nondeterminism because that's a parlor trick, or STM because your ecosystem doesn't use it... there's not much point to worrying about it. Monad implementations in languages other than Haskell fail to take off because there generally isn't even a single thing that is improved by working with it through a monad interface, let alone a family of such things." "[...]It's definitely an interesting idea, and if you are a curious programmer, it's worth learning about this particular interface and what it can do. But it's not something you generally directly take back to your language"
