Why even use DelegateClass ?

     module Foo
       class Bar < ::Bar
         def baz; ...; end
       end
     end

And it's a good question (this is exactly the namespace idea that was
proposed long ago, btw). The only thing in the way of doing this is
Ruby's lack of support for literals. That is to say, if I created an
extended String, Foo::String, then literal string notation within the
scope of Foo should use that. But I am guessing their are possible
subtitles I am missing. Can any one fill us in?
