[racket] match in Advanced Student?

If you look at the docs for ASL as opposed to Racket, you will see that match in the former implements a much simpler pattern language than the latter. In particular, ASL does not support the _or_ pattern. 

Teaching languages aren't Racket. And we should have students sign a language not to put Racket on their resume when they apply for jobs after taking one of our courses.
