> treats the spec a bit like a sacred text, This is not necessarily bad, especially in the context of education. It is well known for ages that a bit of mystery and sacredness makes rather boring moral education much more emotionally charged. There are no active Common Lisp based courses, as far as I know, the last one was that one of the Alegro team, but it was rather an attempt of promotion and has been done without "religious vigor" unlike the famous CS61A by prof. Brian Harvey, which could be viewed as almost sectarian, especially the very first version from 2008. Similar course could be easily made based on Common Lisp, which includes more advanced concepts in CLOS. At least some zeal is good for education. CS61A and the original SICP course by the Wizards are good and still relevant examples.
