personal opinion here.

while i appreciate the sentiment behind nil, it breaks
down for me around the edges.  zero is the one value that
can be assigned to anything.  i think the c standard
thinks about zero like andy worhol thinks about coke.

	you know that
	pointers can be zero
	and integers can be zero
	your ptr can be zero, too.
	a zero is a zero and
	no amount of casting about
	will get you a better zero.

(all things being equal, i'd rather have a coke than a zero,
but i digress....)

what it does get you is longer lines, which many folk still wrap
at 80 characters.  and all things being equal, i find unwrapped
lines easier to read.
