 *   Allow setting a symbol as path in scope on routes. This is now allowed:
 
-      scope :api do
-        resources :users
-      end
-
-    also is possible pass multiple symbols to scope to shorten multiple nested scopes:
-
-      scope :api do
-        scope :v1 do
+        scope :api do
           resources :users
         end
-      end

+          resources :users
