I think, you can easily write something like this
to implement automatic references to parent objects:


module CreatedObject
  attr_accessor :creator
end

class Object
  def create (klass, *args)
    klass.create_new (self, *args)
  end
end

class Class
  def create_new (creator, *args)
    obj = new *args
    obj.extend CreatedObject
    obj.creator = creator
    obj
  end
end

class B
  def child
    @a = create String
  end
end

b = B.new
p b.child.creator


Maybe it is better to protect the access to creator
or even make creator a constant.
It would be better, to overload new, but there is no way to
get the calling object like you can get the execution stack
in Kernel.caller.
IMHO this would be a useful feature as it is already implemented
in some way.

So refering to your case of Procs you can write 'p = create Proc {..}'
and define something like call_proc in Object, which calls the Proc
in the objects context.
