Indeed. Still, that's not hay; pure functional computations may be
well worth delaying. In the Pure language (which is about as pure as
ML -- the name has nothing to do with pure functional programming),
most but not all standard procedures are auto-forcing. This allows
clean interoperation between streams and lists. See
for some elementary examples.
As far as I know, Chibi is the only Scheme with auto-forcing, and it
must be turned on by a configuration option.
