In the description of string-unfold, one of the examples is:

(tabulate-string f size) = (string-unfold (lambda (i) (= i size)) f
add1 0)

but I believe that should be 'string-tabulate,' since I can find no
references
to 'tabulate-string' in other parts of the document.

Of course, it -is- just an example, but nonetheless it makes the
example look
odd.
