Ideas like fold and map where _never_ mentioned in lisp (to exaggerate, every function had to have the recursive implementation with 5 state variables and then a simpler form for the initial call), at no point did higher-order functions or closures make an appearance while rotating a list by 1 and then 2 positions.
The treatment of Prolog was somehow worse. Often the code only made any sense once you reversed what the lecturer was saying, realizing the arrow meant "X given Y" not "X implies Y", at which point, if you could imagine the variables ran "backwards" (unification was not explained) the outcome might start to seem _possible_. I expect the lecturer was as baffled by their presentation as we were.
In general, it left the rest of the class believing quite strongly that languages other than Java were impossible to use and generally a bad move. I may have been relatively bitter in the course evaluation by the end.
