Let me quote Richard O'Keefe, so he won't have to
repeat himself:

   Elegance is not optional

I think making the code aesthetically pleasing is
extremely important. To paraphrase Sir Tony Hoare,
who spoke at QCon last week, software tends to live
much longer than we would like.

Reading other people's programs is difficult to begin
with, even if they have made an effort to make the
code readable. In many cases, no such effort is
apparent to the reader.

Overloading with macros seldomly helps readability.
Helper functions can, if carefully chosen.

And I think this problem is common enough that it
deserves some effort.
