This was discussed briefly awhile back, but it's basically going to
require special handling because macro invocations don't give us the
usual dead simple way of doing it.

Maybe it's easy enough to see if the identifier has parentheses

I probably won't have a chance to take a crack at it anytime soon, so
if anyone wants to beat me to it, feel free.
