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.
