|matz, do you have a preference for a name?

As pointed by objection (c), a constant name is just a reference to
a module/class object.  For example, the following code creates two
references to the A::B module:

  module A
   module B
   end
  end
  C = A::B

Although a module records the first reference name, just for
convenience, having a method to retrieve "a parent of the primary
reference" makes me feel bit weird.

If you show me a real use-case, I might feel different.
