Look, I'm not saying Haskell is easy to learn, it's one of the steepest learning curves I know of in programming.
But I don't think do notation is what trips up beginners (not sure if this discussion is about beginners per se). It is explained by simple mechanical plug-and-chug transformations that I think beginners understand, but am willing to hear if there is evidence otherwise.. I just think it's the other things that will eventually trip them up (I was only responding to specific claims made earlier). Also, on the point of resting on abstractions being a problem, I don't find compelling, because I'm also sure that Python beginners don't understand what "class MyStuff(object):" is really doing, but if the abstraction isn't leaky try don't need to know right away, and they can delve later.
