+     * But the following may not:
+     * - path('route', var)
+     * - path('route', {'param': ['val1', 'val2'] }) // a sub-array
+     * - path('route', {'param1': 'value1', 'param2': 'value2'})
+     * If param1 and param2 reference placeholder in the route, it would still be safe. But we don't know.
+     *
+     * @param Node $argsNode The arguments of the path/url function
+     *
+     * @return array An array with the contexts the URL is safe
+     *
