Subject: access surrounding class


Hello,

is there a possibility in ruby to access the surrounding runtime
type from within a nested class? Module.nesting is not sufficient, 
because it relies on definition time:
 
Following scenario:
------------------snip-----------------------
class A
  class C
    def a
      puts ..::type #access surrounding class
    end
  end
end
class B < A
end
------------------snap-----------------------

A::C.new.a should print "A", B::C.new.a should print "B".
How to do that?

I thought about constants:
class A
  CONST=A
end
class B < A
  CONST=B
end 
or even methods, that get refined in specialising classes,
but all solutions have the same problem: The access of the
runtime type of the surrounding class.

Is there any suggestion or idea, to solve this problem??

Best regards,
Matthias
