highlighted the fact that lists were fundamentally an either-or type
with one branch that was a struct type. It isolated the parts and
definitely helped the students focus on the recipe.
It also had the benefit that the code didn't get too nested or complex,
which was nice.

@image-element, but that's for summoning an image from an outside file;
is there some other form that lets me make use of image literals?

annoying.
So verbatim it is, I guess.

Progress! Executive summary: if your students are losing their test
results window, tell them to stop minimising it.

I wouldn't want to see the test case window be sticky and impossible to
send to the back, but it would be nice if it always came to front when
you click Run and there are some failures.
[0]Well, not always. Sometimes the window resurfaces, and I don't know
why.

it's not obvious whether it's output->string or function-of-interest
being tested, while in

(lambda (x) (string=? (output->string x) "fnord"))
it's clearer that this is a test case for function
On behalf of my students, we'd all like to thank you for the lovely

originally-selected ident or line. It'd be nifty if double-click-drag
caused select-whole-words behaviour and triple-click-drag caused
select-whole-lines, but I'd settle for the drag just extending the
selection on an indivi

backwards semantics of the function. I'm trying to decide if I can just
tell them to avoid overlay/xy entirely, but I don't think I can---although
place-image is great, sometimes you need an offset without cropping.

Sorry, that got long; I've been thinking about this for a few months
now. Let me know what y&#
ester-time, but I may tell the students to upgrade their personal
copies. (Is this change listed in any of the release notes for 5.0.2?)
