Coming from Haskell, I kind of dismissed it on the basis of missing a construct like interfaces/protocols/traits/type-classes, and started checking out purescript instead which is closer to Haskell. Eventually stopped using purescript due to some unbearable compile times (in purescript's defence it was early on in it's development, and it's still pre 1.0). All that said, I'd probably check out elm now only because I've heard good things about it's developer experience.
