Ruby | Referencing Constants

If you write the constant JAPAN in the World class.

 class World JAPAN = '日本' end

Class name :: can be referred to by a constant name.

 World::JAPAN # => "日本"

The class name can be omitted if it is in the same class.

 class World JAPAN = '日本' p JAPAN end # => "日本"

I wrote because the page explaining just that wasn't hit even if I got it in "Ruby constant reference".
