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.
