Elixir Scanner

[zhumo]

I'd love to get an elixir scanner going. I'm wondering, since I don't expect to be able to catch all the little gotchas of a language's syntax, what level of "completeness" for a new language is required? How would I even measure "completeness"?

I've been using the code from here to do some testing (starting with macro/env.ex). If those are not enough one could also use any of the files found in the phoenix framework.

For .expected files of the tests, I'm currently writing the expected files by hand... Is that the only way to do it or am I missing some simpler way?
