I guess it is joke on the joke with a pinch of irony. But multiplication of something in existence like some Ferraris in existence is not really my objection, or question. There is notion that out of of nothing (which is not `nil') being argument, in absence of factors for multiplication, we get result of one. (*) ➜ 1 According to above expression, the empty garage must yield with Ferrari, provided multiplication is done by Emacs Lisp or similar, but not with PicoLisp (it yields NIL). And for two empty garages, if operation is applied on each of them: (*) ➜ 1 (*) ➜ 1 We will get total of 2 Ferraris out of nothing. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
