"The design using a @code{while} loop is routine. The argument passed to the "

"can write a @code{while} loop so that the body of the loop is evaluated if "

"For this design to work, the body of the loop must contain an expression "
"that shortens the list each time the body is evaluated, so that eventually "
"the list is empty. The usual technique is to set the value of the list to "
"the value of the @sc{cdr} of the list each time the body is evaluated."
