Out of curiosity, and if it isn’t impolite to ask, where/when did this bizarre class occur?

Trinity University in San Antonio. The founder of the CS department was a big fan of J and had been there since the 60's so no one really wanted to tell him to stop. J was only used in the Intro FP course. He retired the same year I graduated (2012) and AFAIK the course is now taught in a combination of Scheme, Haskell and ML.

The intro sequence for majors also includes Scala so students there get a pretty good basis in FP.

The most recent version of the course - http://www.cs.trinity.edu/About/The_Courses/cs2322/

They'll probably rewrite the CS department site eventually, but until then, it's a repository of all the information about J you can handle.

Ironically, the reason the CS site hasn't been updated is because it's implemented in J.

So naturally no one is willing to touch it.
