BTW, it might have made sense for a testing framework to add some
macro to do that -- but the forms are close enough so it's not needed,
which is why I like the `module+' thing so much...

(BTW², the only very minor problem is "module" -- imagine telling
students about this: they don't need to know what a "module" is.  But
that's not a big problem, since even without knowing about modules in
the racket sense, they can understand it in the "subsection" sense...)
