Always a strong possibility. Although since I've always received high evaluations in the past, I'm not sure that's a good hypothesis.

I suggest getting in touch with Andrew Runka at Carleton University. He teaches with Racket, albeit at in the context of a programming paradigms course at a third year level. He is more or less successful in doing so.

Source: took the class with him.

Thank you for your advice. I am not going to do that. I have talked to many professors over the past decade who are successful in teaching the class.
