Perhaps you interpreted me a bit too literally. Of course it takes time for internalizing new and foreign concepts. The lecture, lesson or exercise might only take an hour but it may take days or weeks to grok the concepts. And this might mean a lot of practice.
I certainly remember having a hard time understanding this years ago, and my problem was probably the same as yours - the lack of nice books and tutorials (but things are a bit better now) as well as it all being new and foreign. I don't regret putting in the effort, though.
I also do not like the inconsistency in let-in vs. let (do notation), but I guess there's a good reason for that. <- is not strictly "variable assignment" but it seems superficially similar, though (if comparing to imperative languages).
But I don't think these issues can be "fixed" without turning Haskell into something completely different (e.g. something more like ML). Or do you have a good suggestion how to simplify this without making it worse?
