-    #   alias_method :foo_without_feature, :foo
-    #   alias_method :foo, :foo_with_feature

-    #   alias_method_chain :foo, :feature

-    #
-    #   alias_method_chain :foo?, :feature

-    #
-    #   alias_method :foo_without_feature?, :foo?
-    #   alias_method :foo?, :foo_with_feature?

-    # so you can safely chain foo, foo?, and foo! with the same feature.
