First of all, you can only do this when the modules already
exist. (How should the interpreter know whether Little is
a class or module?)

Second of all, I think you need parens because of a
precedence issue:

   foo = (My::Little::Namespace::Foo).new?

Refer to a question I asked last week, something like "Nested
classes and the Singleton pattern", and see Nobu's reply.
