Missing the point of loose languages

Haskell is one of these "you need to wrap your head around these new concepts, otherwise you'll feel like bashing your noggin against a brick wall is the saner option when you actually start coding in it" languages.

That takes more up-front time and effort than most people want to spend. Plus everybody else in your team needs to do the same thing.

I was looking into using Elm (a Haskell-ish language for client-side web programming; transpiles to Javascript of course) recently. Great idea, but where do I get the month that's not in the calendar from, so that I can be up to speed on it?
