Doubt at ActionController::Routing::RouteSet::NamedRouteCollection#clear!

I would like to know if anyone could explain me something:

def clear!           @routes = {}           @helpers =

          @module ||= Module.new           @module.instance_methods.each do |selector|             @module.class_eval { remove_method selector }           end end

The thing I don't understang clearly it's why @module.instance_methods.each do ... it's done since when we create an anonymous Module it has none instance methods:

irb(main):017:0* m = Module.new => #<Module:0x5be78> irb(main):018:0> m.instance_methods =>

Any suggestions?

      @module ||= Module\.new
      @module\.instance\_methods\.each do |selector|
        @module\.class\_eval \{ remove\_method selector \}
      end

end

I don't know this code at all, but module isn't necessarily an empty module (since we're doing ||=)
