The way section 7 of the manual starts, any litatom can have a
property list. When you read the fine print, you see that NIL's property
list can never be anything but NIL. You can GETPROP and REMPROP from
NIL and you can even (SETPROPLIST NIL NIL). Why not be honest and admit
that because of the way NIL is implemented, NIL does not have a property
list?

Why is it that NIL has a NIL property list. Doesn't seem
at all necessary to me.
