P.S. Wikipedia gives for boojum:  “A fictional
animal species in Lewis Carroll's nonsense
poem The Hunting of the Snark; a particularly
dangerous kind of snark.”

“But if ever I meet with a Boojum, that day,
   In a moment (of this I am sure),
I shall softly and suddenly vanish away—
   And the notion I cannot endure!”

Maybe, in some of these schemes, null
is not a primitive, but boojums and boxes
are the primitives, and null is a (safely)
boxed boojum?
