You're using the Lazy Scheme language
which is not really evaluating the
expression until the value is needed. This
should actually happen when the value is
printed, but that aspect of the lazy language
is currently broken and will be fixed in the
near future. For now, you can manually
force the result by using (!! (append ...)).
It is probably better to ask such questions
on the PLT Scheme mailing list, see
http://plt-scheme.org/maillist/ for details.
