I can add to request list. The argument for is that it is a source of "needless" errors. The error applies also if there is a nested box structure, but the top level is an atom.
Perhaps there is a performance reason against it. I would doubt that existing code in the wild relies on the error for any other purpose than to convert the scalar into a list of 1 item. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
