Yes. As a you know well, I firmly believe that such courses should be taught
with teaching languages that are best suited for beginners. No of-the-rack
language is good enough for the job. One of the things we should show students
is that existing languages are bad (in many different regards). It’s the second
course that should make students chafe against the (low) moral compromises of
existing languages (Java, Python), because we owe them an introduction to the
baddities of the real world. (Is this a bad neologism?)
In this spirit . . .

Did Viera Proulx’s testing framework and its reliance on reflection solve the
problem for Java? Given that both languages do come with reflection
capabilities (this makes me want to include #%app and #%module-begin in ISL so
we can discuss good language interposition strategies), the question is
can you mimic Racket’s approach to inside-testing and
outside-observation?
Then you can turn your 3-pager into a real paper. Or someone has already done
it.
