Do notation in Haskell, Scala etc. Nothing else comes close

• tylerhou 8y ago
  You don't need do notation in an imperative language, though.

    Do notation can act like an imperative language, but it can also do a lot of things imperative languages can't (e.g. the list monad, or the continuation monad).

    You don't need the IO or state monads in other languages, but that's not the only useful monad. Applicative functors with their own do notation are pretty cool too.
