I have helper:

module BreadcrumbsHelper
  def breadcrumbs_cache_wrap(key, options, &block)
    ...
  end
end

And i extract part of Controller to module:

module ApplicationController::Breadcrumbs

  def default_breadcrumbs
  ...
end

class ApplicationController
  include ApplicationController::Breadcrumbs

  ...
end

Now i want to connect Helper to Controller. I can do it like this:

class ApplicationController
  include ApplicationController::Breadcrumbs
  helper :breadcrumbs

  ...
end

It's working. But can i incapsulate connection to Breadcrumbs Module?

module ApplicationController::Breadcrumbs     
  helper :breadcrumbs

  ...
end

Unfortunately this code is not working "undefined method `helper'".
