Because using (foo(),bar()) syntax to cram in a compound statement is
just silly and a bad idea IMHO. The real Right Thing is to fix the
compiler and use inline functions instead of macros in just about all of
these cases.
But, given as this puts me in the category of wanting to change other
people's code just for the sake of a preferred coding style, I suppose I
have to cede the point. :)
