Wirth's languages (and books!!) are quite nice, and it always surprised and
kind of saddened me that Oberon didn't catch on more.

Of course Pascal was designed specifically for teaching. I learned it in
high school (at the time, it was the language used for the US "AP Computer
Science" course), but I was coming from C (with a little FORTRAN sprinkled
in) and found it generally annoying; I missed Modula-2, but I thought
Oberon was really slick. The default interface (which inspired Plan 9's
'acme') had this neat graphical sorting simulation: one could select
different algorithms and vertical bars of varying height were sorted into
ascending order to form a rough triangle; one could clearly see the
inefficiency of e.g. Bubble sort vs Heapsort. I seem to recall there was a
way to set up the (ordinarily randomized) initial conditions to trigger
worst-case behavior for quick.

I have a vague memory of showing it off in my high school CS class.
