I have been using Elm for teaching FP (and visualization) for a few years now, and use [litvis](https://github.com/gicentre/litvis) for literate Elm without having to confuse students with TEA or html.

One thing I’ve missed though is the ability for direct file IO and it looks like elm-posix does exactly the job, so really helpful.
