Subject: contained_by method (challange)

okay, after all this time i finally figured out exactly what i am after. 

i would like all my objects to have a #contained_by method that returns a 
reference to the object they are contined by.

for example:

	a = "1"
	ar = [a]
	a.contained_by  # --> reference to ar

another:

	class T
		attr_reader :a
	end
	t = T.new
	t.a.contained_by  # --> reference to t

and so on.

is this possible?
