thanks Alex for this nice foldr. ;-)
however this lazy-foldr can only be used when the fn can stop by
itself (in this case, it's 'and' which is short-circuited) otherwise
lazy-foldr will never get stop.
i think for a good foldr, the evaluation of #(lazy-foldr f val xs)
should be only forced when
but this foldr can't handle the infinite list, am i right?
