I was looking at how SUBLIS worked...
Suppose I was using the SUBLIS property myself.
Suppose I happend to also use the SUBLIS function.
Suppose that I tried to substitute for some symbol that had one of MY SUBLIS
properties (at the front of the property list, by chance).
Suppose I went nuts trying to figure out why the SUBLIS returned the wrong
answer, and why my property lists were being REMPROPed behind my back.
