NIL has more roles than the empty list. It is also the false value.
In the same vein, T is the generic true value, although any value
other than NIL is considered true. And in addition, both NIL and T
are self-evaluating symbols. They are occasionally used for other
special purposes, and this is just one of those occasions.
