Dialyzer and .Proto modules

[rparcus]

Hi, I'm taking a look at this project as a means to learn more about the topic.
I thought about running dialyzer to see what it would find.

Why are dialyzer and the compiler so unhappy about these .Proto modules?

Really interested in this too!

@rparcus I figured it out. The reason is that things were defined as protocols, but not unwrapped into behaviours because Elixir has a generality bug, which the maintainers don't want to fix, where one couldn't make a 0-sized protocol.

This commit works around this bug. And Goo, the FP-centric Elixir fork, incorporates QuinnWilton's bugfix allowing for 0-size protocols into the core language itself.

I'm not sure what to do with this issue.
