+*   Added `ActiveSupport::ArrayInquirer`.
+
+    Wrapping an array in an `ArrayInquirer` gives a friendlier way to check its
+    contents:
+
+        variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])
+
+        variants.phone?    # => true
+        variants.tablet?   # => true
+        variants.desktop?  # => false
+
+        variants.any?(:phone, :tablet)   # => true
+        variants.any?(:phone, :desktop)  # => true
+        variants.any?(:desktop, :watch)  # => false

 *   Deprecate `alias_method_chain` in favour of `Module#prepend` introduced in Ruby 2.0
