+Subject: [PATCH] Fix test suite for ruby 3.0 change for methods on subclass of
+ Array
+
+With ruby 3.0, especially with https://github.com/ruby/ruby/pull/3690 ,
+for subclass of Array, `flatten` method now returns the instance of Array,
+not of the subclass.
+
+To keep the object instance of the subclass, use `flatten!` instead.
