It is of course a matter of taste an style, but functional parts of a program should be separated from imperative parts (cf. e. g. Conrad Barski, Land of Lisp, San Francisco 2011, p. 302). Displaying the results could be done with <code>for-each</code>, which according to R5RS is explicitly to be called because of its side-effects:
<syntaxhighlight lang="Scheme">
(for-each (lambda (item)
(begin
(display (car item))
(display " ")
(display (cdr item))
(display "\n")))
(hofstaedter-male-female 8))
===> #<unspecified>
1 0
1 0
2 1
2 2
3 2
3 3
4 4
5 4
5 5
</syntaxhighlight>
