-      #
-      #   alias_method :foo_without_feature, :foo
-      #   alias_method :foo, :foo_with_feature
-      #
-      # With this, you simply do:
-      #
-      #   alias_method_chain :foo, :feature
-      #
-      # And both aliases are set up for you.
-      #
-      # Query and bang methods (foo?, foo!) keep the same punctuation:
-      #
-      #   alias_method_chain :foo?, :feature
-      #
-      # is equivalent to
-      #
-      #   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.
