Can confirm. I took Advanced Functional Programming for my master's. Of the ~15 people who took the class, the majority scored <=65% or gave up, a few people got pretty good grades because they were reasonably intelligent and willing to put in the work (me), and then there were a few people who scored >=95% because the high levels of abstraction genuinely made things easier for them. That was when I learned that for some people, a monad really just is a monoid in the category of endofunctors.
