Description

Given code like this:

module A
  module B
    class C; end
    class D; end
  end
end

We can get from C to B like C.outer_scope, or to A like
C.outer_scope.outer_scope.

I want to use this in cases where I don't know the outer scope, but I
want to find constants that are "siblings" of a constant. For example,
I can do A::B::C.outer_scope.constants to find the list of "sibling"
constants to C. I want to use this feature when walking objects and
introspecting. For example:

ObjectSpace.each_object(Class) do |k|
  p siblings: k.outer_scope.constants
end

I've attached a patch that implements this feature, and there is a pull request on GitHub here.
