I had not noticed your comment before I said, later, roughly the same with respect to the empty string vs. NULL:

"This empty string discussion is a bit strange to put it mildly. If one
remebers what a string is (a list of characters), then an empty string
is just an empty list, a perfectly legitimate value that one can use in a very much the same fashion as the integer zero. "
