Dialyzer is a good tool to provide type bug… but Elixir is not strongly typed. There were some attempts to add type system, but it’s hard when dealing with messages.
BTW there is this new presentation on dialyxir…
There is MLElixir and LFE (Lisp Flavoured Erlang) if You are up to try.
There is Elixir language server for the last points.
