This is only a problem because you insist on creating partial statements
with the macro instead of full statements.

If the "streaming syntax" would be 

    qFoo(myCategory(), a << b << c);

instead of 

    qFoo(myCategory()) << a << b << c;

there's no "else" to worry about, and it would also solve the problem of 
a "compile time" "null stream":

    #define qFoo(stream, stuff) /*nothing*/

We had this discussion before.
