This is the only really good reason I've found for doing so.

On very rare occasion, when I had only one term in mind for both a
namespace and a base class, this has seemed useful:

  class BaseClass

    class SubClass < self
    end

  end

The fact hat the namespace is a class rather than a module is
inconsequential. In fact, I remain of the opinion that Ruby would be
better if Class and Module were not distinct.
