In the mid 90s, first year computer science at the Australian National University used Miranda, the proprietary language from which Haskell was forking at the time. It was great. When I read SICP later, the first half seemed like a long-winded demonstration of obvious ways to use recursion. Didn't everyone know this stuff?

Much of the language seemed like magic, but ANU had a culture of throwing students in the deep end to keep us humble about what we knew.
