This is awesome! I've been working with Phoenix for a bit now, and aside from the fact hex/phoenix doesn't yet have all the libraries that rubygems/rails have, Phoenix has blown my expectations out of the water. For such a big and complex framework, the entire functional plug system (functional is love, functional is life) makes the whole thing easy to grok in a way utterly unimaginable in a traditional rails framework.
By the way, in case core team is reading, what's the motivation behind removing infer_model_view from the render functions?
