If memory serves, this is to cater for beginning students for whom passing
a single image is more often than not an error.
I (and no doubt others) have written functions above* and beside* to do
"the right thing".

Is there a reason why above and beside (from 2htdp) don’t “do the right thing”
when supplied with a single argument?
I have multiple workarounds in my code that look like:
(if (empty? (cdr lst))
(car lst)
(apply above lst))
Should I just shadow above and beside with my own versions, or
2 matches
