sicp exercise 3.36

;; Exercise 3.36.  Suppose we evaluate the following sequence of expressions in the global environment:

;; (define a (make-connector))
;; (define b (make-connector))
;; (set-value! a 10 'user)

;; At some time during evaluation of the set-value!, the following expression from the connector's local procedure is evaluated:

;; (for-each-except setter inform-about-value constraints)

;; Draw an environment diagram showing the environment in which the above expression is evaluated.

;; Ans:
;; The environment is the environment which is created after evaluating (define a (make-connector)) in the global environment.
