I've played with Elm for a toy project before and I do have high hopes for it. I also think it's the greatest monad tutorial ever - you don't truly miss them until they're gone.

(To clarify: At the time that I last used Elm, the Signal type was a functor, but was intentionally being kept from being a monad for design reasons. Working around this restriction tought me a lot on why I needed monads.

I didn't really understand applicative functors until I was playing with Elm. Working with Signals was pretty fun, and when I found out they were applicative functors, it was like a light bulb going off above my head.

Elm is a really fun way to start exploring purely functional programming.
