Nice - I like Elixir, have only "played" with it but it's a lovely language. Clojure allows side effects as well, you know - sure only in specific circumstances, but a language that does not allow any is very hard to be useful with in the end.
Would love to get your insights on how easy you've found it to re-create common tasks with Elixir, you know like wiring up a quick API to expose this data or that resource, that kind of thing.
