Parse enum abstract from path

@:get('/$type')
function get(type:TheType):Noise;

where TheType is enum abstract

Now I have implemented the server-side part. For the proxy part, apparently the data structure doesn't carry the type of a param but only its name. Not sure how to force-cast it into the underlying primitive type so that Stringly can do its conversion job.

Current workaround is to add an explicit @:to Stringly cast to the type.
