Errata for Exercise 2.19 about eopl3 HOT 5 CLOSED

Thanks so much! I'm probably going to get around to updating the web site
in the next few weeks, and I'll add your erratum.

Coding all the exercises with rackunit tests is fantastic. Two points,
however

1. I'm a little shy about posting the solutions publicly. We instructors
   have enough problems with plagiarism already :( Providing rackunit tests
   for the exercises would be very useful, however, both for people doing the
   book as a course and for those who are using it for self-study.
2. What I'd really like is to replace the homemade testing framework in
   the current code by something using rackunit.

And thanks for your interest and contributions.

Hi Mitch,

AFAIK, this hasn't been reported yet so here goes. On page 44 of the
textbook, we're instructed to implement move-to-left-son and
move-to-right-son, but the example immediately following calls them simply
move-to-left and move-to-right, respectively.

I'm currently working through the text and coding every exercise with
rackunit tests. As a token of my appreciation for co-authoring such an
excellent text, I'd be quite happy to share any and all of my code for you
to use however you please. Perhaps the unit tests will come in handy or
something.

I've recently started a small EOPL3 study group amongst my friends and we're really enjoying the book. We've got access to each others' private repositories but the general public does not—precisely for the reason you've cited. When you have some time, feel free to critique the rackunit tests in particular. I'll happily incorporate any suggestions you might have which might make the test suite something you can use with your students or which we might be able to either release publicly or use to lay the foundations for an auto-grader.

I'd love to see your test suites. Where can I see them? --Mitch
