Let's say I have a plugin for for ActionController. I only want the
plugin loaded if ActionController is loaded.
Rails has put a lot of effort into autoloading only the necessary
files during startup. Is there a good way for the ActionController
plugin to load only when the ActionController module is loaded?
For example, most plugins would do the following:
ActionController.class_eval do
include UberControllerPlugin
end
The above lines cause all of ActionController to be loaded for all
tests and server startups. Is there a way to "autoload" the plugin
only after the ActionController module has been referenced?
