Should we ever be storing a NULL pointer?
Yes, we should, because I use interchangeably the "lisp object"
description entry for actual lisp objects and for pointers to lrecords
since, memory-wise, they're identical, and I don't like duplicating
code. There are instances were these pointers are null.

Adjust it and you're welcome to do such a change.
