Sure, I would, if I ever got to teach macros. I teach Scheme to non-majors who are lucky if they get to HOF's in a semester. I teach Scheme to CS majors, but only for a third of a semester, so at best I get to mention the existence of macros. I teach C++ for more than half a semester, but there are so many difficult and necessary things to cover in C++ that I don't get to parameterized macros.
