I am not convinced by this proof. > There is a monoidal zero wrt Append (,) for any array > except when its shape is 0$0. This sounds like a property of append. As an analogy, consider reciprocals -- you would not argue that 0 is not a finite number because it does not have a finite reciprocal. Arguing that you cannot append to a scalar and get a scalar seems to me to be similarly futile. Append is an operation that is guaranteed to give you a result that has some kind of list structure. That is all. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
