desired result without having to resort to macros that invoke
macros, but as
always, there are many ways to get where you're going.
I agree completely about the trip-up potential of macros, but the
niftiness of macros is just too seductive. I can't resist. I confess
I use them extensively to simplify my C code (for reading) while
complexifying it (for debugging). I often wish for them in scripting
situations—just to cut down on typing—but imagine the nightmare for
newbies!
