 Lisp is a great language to get into the functional way of thinking and LFE is Lisp 2+ which runs on the greatest platform (personal opinion).
 Elixir's Mix is a great (or the greatest) configuration/package/build manager, so why not use it to compile LFE?

 For now the source is very simple and uses  an [idea](https://github.com/elixir-lang/elixir/blob/e1c903a5956e4cb9075f0aac00638145788b0da4/lib/mix/lib/mix/compilers/erlang.ex#L20) from the Erlang Mix compiler.
 All works well, but requires some manual work and doesn't support LFE compiler fine tunning, so that's what we'll be after next.
 
-1. Add task for running LFE tests. What kind of tests? Will see...
+1. Make it possible to add options when running `mix test.lfe`.
 2. Automate the installation & setup process in a way. Maybe by using something similar to the Phoenix generator tasks.
 3. Pass more options to the LFE compiler, using mix configuration.
 4. Use LFE syntax for configuration (not sure this is needed, really).
