Exercise 2.7
Parameter passing in Scheme *

Familiarize yourself with the parameter passing rules of Scheme by trying out the following calls:

  ((lambda (x y z) (list x y z)) 1 2 3)

  ((lambda (x y z) (list x y z)) 1 2)

  ((lambda (x y z) (list x y z)) 1 2 3 4)

  ((lambda (x y z . r) (list x y z r)) 1 2 3)

  ((lambda (x y z . r) (list x y z r)) 1 2)

  ((lambda (x y z . r) (list x y z r)) 1 2 3 4)

  ((lambda r r) 1 2 3)

  ((lambda r r) 1 2)

  ((lambda r r) 1 2 3 4)

Be sure that you can explain all the results
