Speed up development by only reloading classes if dependencies files This can be turned off by setting config.reload_classes_only_on_change to false.

Extensions like Active Record should add their respective files like db/schema.rb and db/structure.sql to config.watchable_files if they want their changes to affect classes reloading.

Thanks to https://github.com/paneq/active_reload and Pastorino for the inspiration. <3
