+    # an in-memory hash. Relies on the Base backend.

+    # The implementation is provided by a Implementation module allowing to easily
+    # extend Simple backend's behavior by including modules. E.g.:
+    #
+    #     module I18n::Backend::Pluralization
+    #       def pluralize(*args)
+    #         # extended pluralization logic
