What do you think about having render take a view (the .rb file) instead of the mustache template? I kind of want to put my mustache templates in app/mustache_templates/... (so I can share them easily with client-side JS) and my mustache views in app/views/... (e.g. app/views/posts/show.rb app/mustache_templates/posts/show.html.mustache)
