It's not just making it mathematical. Think of how "undefined" relates to
"set". My guess, after a while of reading Hans on "undefined sets", is
that it's "undefined" in the sense of "it has a selector that is not one
of the five magic selectors of pd", and that doesn't even mean those that
are not defined internally in pd, because that would exclude "set",
"reset", and a few dozen others. That's a quite peculiar use of the word
"undefined", and not any of my first 242 guesses of what "undefined" might
mean in Pd.
