I would assume the pother is because OIL and NIL are macros that provide

serialization. It should be relatively easy to create an XIL macro based
on OIL or NIL however.

Please show us how to then!

Any standard logic text establishes that

o AND, inclusive OR, and NOT are together universal,

o NOR alone is universal, and

o NAND alone is universal.

Thus, in an obvious notation,

XOR(a,b) =df (a | b) & (¬(a & b))

What is all the pother about?
