Let's build our own code reloader for Rails, shall we?
Run this inside rails/railties:
$ grep -rn "eager_load_paths" .
You should get the results from Rails::Engine::Configuration and Rails::Engine. As you know, each Rails application is actually a Rails::Engine and Rails::Engine::Configuration is that thing wrapped inside Rails.application.config block.
