require_dependency(file_name, message = "No such file to load -- %s.rb")
Interprets a file using mechanism and marks its defined constants as autoloaded. file_name can be either a string or respond to to_path.
Use this method in code that absolutely needs a certain constant to be defined at that point. A typical use case is to make constant name resolution deterministic for constants with the same relative name in different namespaces whose evaluation would depend on load order otherwise.
