Picking up the latest version I'd expect to be able to do something like the following

@RequestLine("GET /users?name={name}")
public JsonObject getUsersByName(@nAmed("name") String name);

Unfortunately this doesn't seem to work. The default encoder receives a LinkedHashMap and complains about it not being a String. The GsonEncoder copes fine with it but the end result is that a POST is made with the query parameters encoded into the body.
