ASIDE: I've been using learn you a haskell for great good!http://learnyouahaskell.com/, and found it helpful, insightful and the examples nicely paced so you can treat them as exercises as you go.... up until the module chapter, which is more like a reference, very long, detailed, tedious. I got up to here
http://learnyouahaskell.com/modules#data-char (check out how small the scroll bar slider is on the right - this is a big chapter).
yeah, it's definitely more of a reference. Personally, I just skimmed through it and moved on. The purpose of a chapter like that is to give you a rough idea of what's out there. When you'll actually need something, you'll be looking it up anyway.
Just move on to the next chapter if you find it tedious. The book goes back to the original style in the subsequent chapters.
Did this stop you or how did get past it?
