This would be much more work than the other microprojects.  The ones
that I wrote were mostly one- or few-line changes that didn't require
the student to learn a lot of context.  (And most students struggled
mightily with even those.)  So I'm not sure this task is suitable.

Other feedback welcome.  We're pretty much out of microprojects, which
is possibly even worse than having difficult ones.
