Sometimes, to debugging, it is very interesting to see low-level Erlang code generated by Elixir compiler. This simple task can help with it.

$ mix debeam Some.Module > some_module.erl
$ cat some_module.erl
-compile(no_auto_import).

-file("lib/simple_module.ex", 1).

-module('Elixir.Simple.Module').

-export(['__info__'/1]).
