Module declaration with inner classes in Ruby

For example, I have file list.rb

module List
 class Base
 #...
 end
end

So in outer files this class would be accessible as List::Base.

Let's say I create another file list_base_extenstion.rb

I can do this:

module List
 class BaseExtension < Base
 #...
 end
end

Or 

class BaseExtension < List::Base
end

Is this equal?

Or then BaseExtension will not be considered the part of module, but inherit directly from List::Base?

No, it's not equal. If you use

module List
  class BaseExtension < Base
  end
end

you define a class called List::BaseExtension that inherits from List::Base. Instead, with

class BaseExtension < List::Base
end

you define a class called BaseExtension that inherits from List::Base. The class will be defined outside the scope of List.
