@jacobb: What it boils down to is that I just need to write a custom output system for eunit.

Also, the erlang VM is super slow, which is a huge pain. Maybe if I get frustrated enough with it I might forget to be lazy and fix it.

It already sort of is. If you go to your settings an enable the Kumite feature you can see it there. Kumite is still under development at this point, as well as Erlang support, but its a start.

Is Erlang coming to codewars?

I upgraded to R17 last week... hopefully you'll see it soon on the site!

Awesome, thanks!

Thanks. I've added a github issue. Feel free to tackle it if you have the time to get familiar with the OS project.

In the kumites section, the erlang vm used is R16B03. Please upgrade it to R17+, since the introduction of "Named Funs" makes it far easier to write recursive functions (Maps were also added) http://joearms.github.io/2014/02/01/big-changes-to-erlang.html.

The 'init:stop()' command stops the Erlang VM/Top level process. We have to do that because otherwise the VM will time out the kata output window (the "this took more than 6000ms" error).
