They already said it was helping them outside Haskell. I can confirm that my long affair with Haskell (and I still use it for private projects) did so as well.

They already said it was helping them outside Haskell. I can confirm that my long affair with Haskell (and I still use it for private projects) did so as well. On the other hand, it also makes for an often frustrating experience of "this would be so much simpler/easier if it were Haskell or at least had x", where x could be algebraic data types, higher order types, Monads, Applicative Functors, dependent types, laziness, and so on and so on... EDIT: Addendum: Rust scratches some of that itch and seems more and more accepted in the workforce world, so at least that's a good direction we're moving towards.
