The binding construct let defines Scheme block structure. In a let expression, the initial values are computed before any of the variables become bound. Evaluate these expressions by hand showing the effects of lexical binding in Scheme. A. (let ((x 2) (y 3)) (* x y)) Output: B. (let ((x 2) (y 3)) (let ((foo (lambda (z) (+ x y z ) ) ) Output: (x 7 ) ) ; call foo (foo 4))) The binding construct let defines Scheme block structure.
