Looks like your playground is based off Ellie, which is a great choice. However, it seems that there is an issue with downloading the Elm compiler. I'm getting a network failure from ellie's CDN(NAME_NOT_RESOLVED).
Other than that, thank you for this, it is super interesting to me as I am a huge fan of both languages, and lack of type safety has always been my only misgiving with Elixir/Erlang. I'll have to take a spin this weekend.
fwiw the latest release moved the compiler back to the server. the ghcjs stuff proved too difficult to deliver a good experience to everyone. a naughty cdn was just one of many woes.
