 Write it like this

J> module M
J>   def self.append_features base_class
J>       base_class.class_eval {@@base_class = self} # fails
J> #      base_class.class_eval "@@base_class = self" # ok
J>   end
J> end

   module M
      class << self
         def append_features base_class
            base_class.class_eval {@@base_class = self}
         end
      end
   end
