Hi

Thanks for your contribution.

But I'm still no happy with the default -S mix arguments. I think you won't always run iex in the context of the application. iex -S mix will run the default mix task which is mix run if you doesn't set another one in your mix.exs file. So as an example, if you would do this in the context of the elixir source directory, it would compile the whole thing first...

I think the adding of the universal-argument is a good idea. Actually I would like to have something like inf-ruby in the near future. So for now I think the universal-argument is a good solution, and you don't need your -S mix anymore. ;)

So please update the branch.

Cheers

@tonini I'll have to check out inf-ruby (though a bit daunting for an elisp beginner). For now, I've rebased the branch to get rid of the -S mix commit. How would I write a unit test for this?

Thank you! :)
