Environment diagram

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.
