one side effect is that all instance methods of R are available at the module
level too.  i generally do that this way:

   harp:~ > cat a.rb
   class Module
     def export meth
       module_function meth
       public meth
     end
   end

   module R
     def foo() 42 end
     export :foo
   end

   p R.foo

   harp:~ > ruby a.rb
   42

what that what you were after, but wholesale?

interesting trick.

regards.
