I am not against having such a macro. I am against any form of treating an empty sequence of preprocessing tokens and whitespace separations (or one containing only whitespace separations) as a non-element in a data structure. "Empty" is a data element just as any other. E.g. () is not a nullary tuple, it is a unary tuple, and so on. Regards, Paul Mensonides
