| 1. Is this desire politically correct?

  well, you wouldn't get a complaint from me.  that's why NIL is there.

| 2. If it is, there should be a way to declare the variable's type.
| How do I do that?  

(or <whatever> null)

  note that this won't buy you anything.  you need to declare the type of
  the object _after_ you have determined that it is not NIL to get any
  performance benefits from the declarations.

| 	(define-format-command #\= (lambda (stream obj atp colp &rest pars)))
| is dead?

  looks like it.

  God grant me serenity to accept the code I cannot change,
  courage to change the code I can, and wisdom to know the difference.
